My favorite things from 2010

Here are some of my favorite things from 2010, some techy, some not so. Merry Christmas everyone:

Lenovo Laptops - Built like a tank, styled like a brick, Lenovo (Formerly IBM) laptops are certainly not considered pretty. But that's part of the appeal to me. That, and the fact that they just seem to go and go means they are always top trumps for me

Ubiquiti Wireless (www.ubnt.com) - For years I used the high street branded wireless gear (Dlink, Netgear etc.) and then I discovered Ubiquiti and have never looked back. The most reliable, well put together tech gear I think I've ever used. And cheap. Ubiquitous.....


Cactus Supertrousers (www.cactus.co.nz) - Bombproof trousers made right here in NZ. Feel like stiff cardboard when you first buy them, but after 2 years they are as comfy as an old gin soaked friend

Leatherman - Laugh, but yes, I am one of those tools that carry a multitool around on my belt all the time. But I use it every single day and if I forget it it's like having one of my hands cut off

Microsoft Active Directory - If you've got more than 15 or so computers to look after, nothing comes close.....

Group Policy (www.grouppolicy.biz) - and if you want to manage and automate everything on your network, then Group Policy is the most powerful friend you have

Google Apps - Want to write a document, and share it with others so that they can write on it, at the same time,via the web? Get Google Apps. Love them or not, Google have created a cloud based product that is so good it's scary. Oh, did I mention that it's free?......

iPhone 4 - "Tried the rest, now get the best"........ Seriously, good that Android and Windows Phone are, they don't come close to the iPhone. I've used everything and I always come back to it. The 4 is the most complete handheld device I ever used, oh, and apparently you can make phone calls on it too.....

Danny Macaskill. Watch clips of this fella and his amazing skills on a bike on YouTube. Makes me want to be 18 again.... And braver than I am now....

The quest for the perfect classroom speakers....

I've written previously about my quest for a perfect speaker system for the classroom. One that finds that balance of ease of use, value for money, and of course great sound. Well this week I discovered the M-Audio AV20 and AV40 systems and I think I've finally found the perfect system.

If you are looking for a powered, 2.0 speaker system thats well made, and well priced compared to other mainstream brands, then these are well worth listening to

Laptops for the classroom

See this 'Google Techies for Schools' post about trying to find the perfect laptop for the classroom. Having researched this for the last few months, the Toshiba T130 is the winner. The HP5320 is a better notebook all round, but the 4 hour battery life doesn't cut it unfortunately....

And I wonder why things seem so complicated these days.....

I Love the Internet. There, I said it, and I'm sure it won't come as a surprise to any of my friends to know that this is true. Occasionally however, I am bemused, and agitated at how our lives, which if you read the small print, should be getting simpler, are so ridiculously complicated these days. And I wonder if the good old interweb isn't to blame.

Case in point. Sunday saw the last breath of my trusty (?) iPhone 3G. Over the last 18 months I've dropped it so many times I've lost count, but the fall from my pocket to the concrete floor by the barbecue was just too much, and the screen and case smashed into lots of little pieces. I was a little dismayed, but it's recent poor performance since the OS4 update was driving me nuts anyway, so I wasn't too upset. Other than the inconvenience of not having a phone for a few days, I'll be honest and say that I was already rubbing my hands at the prospect of a shiny new iPhone 4......

Right up until the time I visited our local Vodafone retailer that is.......

They eagerly wrote me a letter to say that they had checked, and yes, the phone was beyond repair, and provided me with a quote for $1099 NZD to replace it with an iPhone 4. Having initially only paid $549 NZD for the phone from the Vodafone online store for the 3G, I queried the cost of the replacement, and the salesman explained that the original cost of the handset is subsidised when you first sign up to a plan (which I knew already I suppose). And obviously comparing an iPhone 3G against and iPhone 4 isn't a fair comparison anyway, so I happily accepted the quote, knowing that my insurance company would hopefully pay for it anyway.

All was going well right up until the point where I asked the salesman if they had an iPhone 4 in stock, and whether I could come back tomorrow to get one. He then proceeded to explain that, even though they had iPhone 4 posters throughout the store, and had just quoted me for a replacement, that they couldn't sell me one as "at the moment they are only available from the online store". Having dealt with the Vodafone store previously, alarm bells started ringing.

So later in the day, I get confirmation that the insurance company have approved the claim, and that I should go shopping for a new iPhone, and send them the bill, minus the $250 excess. I go to the Vodafone online store as directed, to find that the iPhone 4 is only available to buy with a new iPhone data plan. But I've already got a data plan, I just want to buy a replacement handset for the one I broke on Sunday. But I can't do it. I can go to the Apple online store and buy one, but it's $25 more expensive, and I have no idea whether it will work on Vodafone, and no idea how I can get my existing number put onto a MicroSIM (which the iPhone 4 uses) without going through Vodafone. I call Vodafone, who tell me to go into my local retailer........

Familiar circles. By now, I should be used to it. But for someone who spends his life championing the internet, this is the increasingly all too familiar situation I find myself in. Local retail is disspearing because it can't compete with the web, but the web falls short when it comes to physicality and flexibility. I understand the reasons behind it all, and I find it frustrating. I can't begin to imagine how the average day to day joe public gets on. Maybe that's the problem.

So. Day 2. Vodafone store here we go again..........

Lego Mindstorms

Thought I'd post this for any of you running Lego MindStorms NXT on your network. 

An issue that has cropped up for us has been the save location of the 'MyBlocks' components. Although MindStorms allows you to save the project files wherever you like (our students put them in their home drives), the 'MyBlocks' components don't provide a traditional save as dialog box. After a bit of digging we worked out that they are saved to "C:\documents and settings\%username%\My Documents\Lego Creations\Mindstorms Projects\Profiles\Default\Blocks" which for us (and I'm sure most networks) is a problem. Students have no access to C: and the profiles are deleted on logoff, so our students would work on a PC, create and save a project, then add some MyBlocks. On logging on to another machine, the project would open, but the MyBlocks would be missing.

To get around this we did the following:

- grabbed a copy of the 'settings.ini' file from "C:\documents and settings\%username%\My Documents\Lego Creations\Mindstorms Projects\Profiles\Default\

- edited this file and changed the "Data Directory=/C/...." to "Data Directory=/H/"

- copied this up to a public share

- created a script that xcopies this file to "C:\documents and settings\%username%\My Documents\Lego Creations\Mindstorms Projects\Profiles\Default\" then starts the Mindstorms program

- Edited the desktop shortcut on the student machines to run this script instead of running Mindstorms directly

So the student runs the shortcut, xcopy copies the ini file, then Mindstorms runs (hardly any delay really). When they save a MyBlock now, it goes into their Home drive so it now becomes portable across the network

If anyone knows an alterantive or better way, please comment

Be quiet, I AM SPEAKING.......

In my eternal quest for the perfect classroom speaker system, I'm now evaluating the Creative T20 Series 2 system.

A bit of background first. Throughout the school we have a mixture of classroom audio systems, from basic 2 channel speakers that sit on the teachers desks, to big, overblown 'surround sound' amplifier/DVD/VCR systems that were fitted before I started here.

To make things consistent from one classroom to another, I'm trying to standardize the systems in the majority of classrooms. The first thing I'm doing is removing the surround sound systems where I can. Most of the teachers find them too confusing to use and my technician spends an inordinate amount of time explaining (yet again) how to switch from the DVD input, to the laptop and back again. I'm working on the premise that all of our full time teachers have laptops with DVD Players in them and they simply don't need stand alone DVD players any more. So out they go. VCR's are a bit more troublesome. As of yet we don't have a 'video on demand' system across the school network, and a number of departments still use VHS tapes. So for now, I'm leaving those classrooms alone. Each of our classrooms has a docking station for the HP laptops, a projector (some ceiling mounted, some not; more about that in another post I think). My aim is to have a simple system whereby each and every time a teacher docks their laptop they are automatically connected to a wall mounted sound system and the projector. Sounds simple enough, and not unreasonable for teachers to expect I think.

There have been a few issues with achieving this though, including screen resolution problems (solved with Windows 7, the latest Intel drivers and a bit of tweaking). The biggest problem has been trying to find the perfect speaker system. After considering things carefully, I decided that the speakers needed to be:

1) Powered (i.e active 'computer' speakers)
2) Wall mountable
3) Of sufficient quality to fill a room and not distort
4) Ideally 2 speakers with no sub-woofer

I wanted to get away from amplifiers and switches (just another thing for the teachers to have to think about) so the speakers had to be 'self powered'. They need to be able to be mounted up on the wall with brackets or a home made shelf. They obviously need to be able to do the job, and ideally I want a 2 speaker system.

There are a plethora of active speakers on the market, from cheap $20 tinny boxes to $1500 B&W systems. The budget was really no more than $200 per room, and in that range the the Creative T series fits the bill well. I have used the T10's previously in smaller classrooms and they have been good. They manage to fill the room, they are relatively easy to install and power, and they don't 'boom' until you push the volume over 75%. The T20s cost approximately twice as much, and early testing makes me think they are definitely better than the T10's, but not twice as good. They still boom a little at high volume but they definitely hold it together better than the T10's when say playing a DVD in class. I'll get them mounted up over the next week and will post more when I do

Forcing Google Apps to use Chrome instead of Internet Explorer

Continuing on with our roll-out of Google Apps for Education here at school, we have been struggling a little with browser compatibility.

First off,  it's obvious, and it's inevitable, but Google Apps is much better in Chrome than it is in Internet Explorer, hands down. I'm not entering into the browser debate, and in lots of ways I don't really have a browser preference but Google Apps simply looks, feels and functions better in Chrome, and as new features become available in Apps, we are finding that IE won't even run some of those features anyway (Wave, Drawing etc.). There is a plugin available from Google (Chrome Frame for IE) that enables Chrome functionality within IE, but as with most things Google, there doesn't seem to be any offline installer that we can use to push out to all of our client workstations. We will keep looking though, because if we find one, it will solve most of the issues we are having.

Another simple solution would seem to be just to roll-out Chrome to all of our workstations right? Wrong. Again, Google doesn't make this easy. Although there is a standalone installer for Google Chrome it installs itself into the user profile directory rather than the common 'Program Files' and for a few reasons this simply won't work on our network. Again, no easy fix for this yet either.

Having spent a few hours on this, I went and did something else to clear my mind, and I then remembered 'Portable Apps'. Portable Apps is a collection of applications that have been packaged up to run on portable media (i.e USB keys) but they often run just as well on a network, without many of the hassles of applications that need to be 'installed'. We use Audacity and WinFF as portable Apps here and students run them seamlessly across the network. There is a portable apps version of the latest Chrome browser and I'm pleased to say it works a treat. I simply installed it to a network share, then created shortcuts in the student profile that run the portable version of Chrome, and call up the particular address for each Google Apps component on startup. So the students now have separate shortcuts on the desktop to Google Docs, Google Sites and Google Calendar that force run Google Chrome. Job done so far. We still have links on our Intranet page that point directly to the web addresses of Google Apps, and these will open in the default browser (which is IE on most of our workstations) so that is the next problem. We'll keep looking for the Google Chrome Frames installer, and maybe an easy way to push Chrome out to workstations, but for now, it will do.

18/11/10 Update on this, the Google Chrome Frame installer is now available as an msi which can be pushed out via Group Policy

More livin' and learnin'..

It was a 'teacher only' day on Friday and as most of the staff were in a PD session I used the time to tidy a few things that had been niggling at me for a while.

One of those things was to increase space for my virtual 'Windows Deployment Services' server so I could store more images on it. In order to do this, I decided to change the VHD file (Virtual Hard Drive file) of my virtual print server from a fixed disk to a dynamic disk, to claw back some of the 64Gb of space from the print server to use on the deployment server. The print server was only using 11Gb of it's drive space anyway, so I figured that space was probably better allocated somewhere else. Although I had never converted from a fixed to dynamic disk before I have gone the other way a number of times and it's always worked well. So I went ahead and did the conversion, but in doing so I ignored the error message regarding the snapshot that I had loaded against my print server telling me that there could be a loss of data. Stupid move. The conversion went well, I booted up the print server, but I couldn't logon to the domain. Strange I thought, but maybe something to do with trust relationships etc. (?). So I logged on as the local administrator, removed the server from the domain, rebooted, rejoined the domain and hey presto that fixed that problem. As far as I was aware that was it all sorted.

I had a days leave planned today and yesterday was a public holiday. I had a text message from a teacher yesterday telling me they were having printing problems and although alarm bells started to ring somewhere in the distance, after logging in from home and running some basic checks I assumed it was just error between keyboard and seat and left it at that. After my technician had texted me this morning in a state of distress that everyone was having print problems, I began to regret ignoring those basic checks. I won't go into everything but it turns out that by ignoring the snapshot error I had basically reset the printer to a state of 6 months ago, when I first set it up. I had used the .vhd file of the print server and ignored the .avhd snapshot file when I had done the conversion. In itself this wasn't so much of an issue but what was screwing things up was that the databases that handle our print cost recovery (Papercut and Monitor Business Machines) had gone back to as they were six months ago too. Nobody had any credit and none of the new printers I had put in since six months ago existed.

Luckily, I had made a manual backup of the original .vhd and .avhd files and after restoring and merging the snapshot back into the .vhd things are back to as they were. Phew. Again, so many lessons learned. The main thing I think is that although living in a Hyper-V world has made SO many improvements to things, it's also made me a little blase about what I do with my servers. I have to remind myself that even though they are virtual servers they can still stuff things up just as well as a real server when I get it wrong  ......

Heart stopper

I happened to be in work today using the workshop and whilst I was having lunch decided to run the HP Proliant Support Pack on my three main servers, seeing that nobody was around to notice when they were offline for a few minutes. Made the classic mistake of telling my wife that I was ready to be picked up before doing the last server, just so I wouldn't have to hang around (which is what I am now doing anyway....) So PSP updates BIOS and firmware in P400i controller, server reboots and I get the heart stopping, stomach churning "no boot disk found". Long story short anyway, firmware update has put the 2 logical drives in failed state. I discover this after seriously rethinking my career kind of hour.

Anyway. Booted from SmartStart CD reenabled drives, ignored all warnings that all the data was probably screwed and prayed as the server restarted and booted up fine. A few data integrity checks later and I am relieved, but cold waiting for my lift, and a little older and greyer.

There are so many lessons and morals to this story that I don't know where to start.....

Consumer madness

I love living in this country, but often the lack of options when it comes to buying things drives me insane. Case in point. I’m trying to buy a new bike for my daughter at the moment, and I can’t buy the one I want. I’ve researched it and found that the best one is a Scott Mach One Jr. Most of the others are mass produced steel framed bikes that weigh as much as a small car. The Scott is light, well made, gets good reviews and according to the Scott website is readily available in New Zealand. Most importantly it is adjustable enough to last until she is 8 or 9 unlike the other bikes that will only last for 18 months or so. However, having spent the last 3 days on the phone and email to pretty much every bike company in the country I have worked out that they all buy their bikes from one wholesaler and they, and the wholesaler are out of stock and another shipment will not be coming until October. End of story.

I understand that we are victims of our remoteness here, but the socialist in me can’t bear this lack of competition. It pretty much applies to everything that you buy in New Zealand. Whiteware, cars and definitely computers.  In every industry there is the manufacturer, an importer (generally only one or two), the wholesaler, and a couple of retailers thrown in for good measure. We as the consumers get shafted from all directions – price, availability, quality and after sales service (which also is surprisingly bad here in NZ)

Maybe, it’s just me. Maybe I need to research less and just buy what’s on the shelves and be done with it. Put my logical side of me away and stop questioning this stuff. Otherwise I’m going to end up even more bitter than I already am..... If that is at all possible.....

Snobbery

I am trying to understand the inverted snobbery that is associated with computers and technology in general. The attitude that I come across daily that computers are somehow 'below' many people. That they are too busy or important to have to think about these pesky computer things. Or even better the certain pride that some people have about being (can't believe I'm even going to write it) "Computer Illiterate"......

SchoolZone woes (again...)

First day of term for most New Zealand schools today and I can't believe that the SchoolZone email system is not working! I shouldn't be surprised, as it's run by Telecom, but come on, probably the biggest ISP in New Zealand Schools and I'm greeted by a "we are having problems with email and are working on it " message when I ring for support. The phrases "Quality of Service", "Redundancy" and "House of cards" spring to mind....

Parental responsibility

A friend asked me today what I thought we should be doing as parents to protect our children in a connected world. I could have reeled off some of the well known pointers like keeping computers and cellphones out of childrens bedrooms, parental controls on PCs etc. but when I gave it some thought I began to think that although those sort of things might 'help' in the short term, they are really just ways of ignoring and delaying the issues. I think that the root of many of the problems related to children and the online world lie in the hands of parents themselves. First we replaced books with TV, then the VCR replaced TV. DVDs replaced the VCR and then along came the computer and for many parents it was just another way of keeping children occupied. Although most parents have come to realize that computers and the Internet is so much more than a distraction, I'm sure that the majority are still largely ignorant to the intracacies of what existing online means to young people. So my answer was that the best, and really the only thing to do was for parents to realize that they have a duty to upskill themselves so they do understand. Parents can no longer bury their heads in the sand or claim ignorance about computers, the Internet or technology in general. They need to learn, and then they need to communicate and keep communicating. To be continued......

iPhone 3G Wifi Speed on Zyxel HW660 Router

More a  reminder for me than a real post, but if anyone suffers from the fairly common "iPhone 3G/3Gs slow wifi" issues (see here, here and here), follow the instructions in the third link and things should come right. I don't claim to really understand what RTS/CTS means (Zyxel's definitions are here) but having recently swapped my router at home for a Zyxel HW-660-D1 router (thanks Mike), I was suffering from incredibly slow wifi on my iPhone (all other devices were fine, just the iPhone's were having problems). I spent ages trawling the interweb and eventually improved things by changing these advanced settings on the router:

  1. Disabled 802.11G+ (and just using 802.11G instead)
  2. Changed to RTS/CTS Threshold to 2432
  3. Changed the fragmentation threshold to 2432
Although it's not blisteringly fast, I can at least listen to BBC Radio Cumbria using WunderRadio without it buffering all the time.

Decent projector installation

Ah, the quest for a decent projector installation continues. Easy you'd think, buy a bracket and stick it up. OK. So what about the cables? How and where do I run them, what do I use, who do I use to do it? Having done a bit of this sort of thing myself in a previous job I have been disappointed by the installs that we have had done at school so far. With another classroom due for a ceiling mounted projector, sound etc. soon, I think I might do this one myself and see how it goes.

Dissapointed....

Yesterday I attended the "Future of ICT In New Zealand Schools" symposium, and it was unfortunately a real let down. I'd only found out about it the day before and was excited at the prospect of attending something with such a grand title. I took along one our ICT lead teachers and chatting with her and others afterwards, there was a definite feeling of confusion and that we had been a tad mislead by the title.

What the symposium turned out to be, was the launch of the new online version of the 'Computers in New Zealand Schools' journal (which in itself looks really good by the way). This was preceeded by a rambling presentation by Ed Strafford from the MOE on..... well, none of us were really sure what it was on actually (Sorry Ed...). There was then a panel presentation by three speakers, including Niki Davis, who I had heard before at U-Learn. Although there was nothing intrinsically wrong with the presentations and subsequent discussions, it just didn't all gel together and (comment if I'm wrong), most people left feeling a little dazed and confused. No fault of the speakers I think, more the organisation of it all perhaps.

2 things that stuck out in my mind were 1) Too many of the presentations I have seen by people from the MOE are badly organized 2) I am always amazed at the number of people involved in ICT that still use pen and paper for taking notes....

I did join the e-learning research network, which looks excellent, and I remain positive that what we are doing in our school with ICT is on the right track. I just feel a little deflated. I spend my days trying to help our staff understand the benefits of deep integration of ICT into their teaching, and often find myself defending technology to the naysayers. Sometimes though, I wonder if they are right....

To pay or not to pay

Faced with the high cost of the Adobe suite of products (Photoshop, InDesign, Illustrator, Dreamweaver etc.) we have been discussing the pros and cons of rolling out free or open source alternatives. Amongst many other articles I recently read this article on interface magazine which is a good primer on some of the good bad and the ugly. I am torn really. The rebellious, anti-establishment side of me loves the idea of software that is developed "by the community, for the community", and did I mention IT'S FREE! (well sort of...). However, the conservative network manager side of me has always been disappointed by the lack of polish on all of the alternatives I have tried. An example would be trying to use Kompozer as an alternative to Dreamweaver last term. It worked, but managing it in a network environment where kids are moving from one machine to another like rabbits was virtually impossible. Every time they moved to a new machine, they had to setup their sites from scratch, and this became (ahem...) a little tiring for them. Dreamweaver. Roll it out via an msi to all machines in a lab, without even visiting said lab. Kids logon, setup site once. Work on any machine and hey presto, it just works (for me and for the kids). Now this is a very small example, but I am writing it because it is typical of the seemingly small, but deal breaking issues that arise when it comes to open source/free alternatives. As a parent, I'd like my kids to be able to use stuff at school that they can use at home (for free), and it seems daft that in these times of breaking down the barriers between home and school using technology, we are considering spending a lot of money on something that for most of our students (unless of course they download a non-legal version) would not be able to run on their home computers. I'm not ready to throw out my Microsoft Servers and Desktops (and to be honest I probably never will be), but maybe I just need to work harder on making some of these alternatives work in my environment..

Google Talk / Google AppsAccounts

Google Talk is a basic instant messaging program and can be used as part of Google Apps for Education. My Google Apps (GApps) users can sign in using their accounts and, as I had just had a request for an instant messaging system for the staff I thought this was a great thing.

Well it is, but as always there's a 'gotcha'.... The problem is that we don't really want instant messaging for the students. Easy you say, just don't install Google Talk on the student machines? Well yes, that does help. However, in their wisdom, Google decided to build the 'chat' feature into Gmail, and I am rolling out Gmail to all of my users. So the students bring up a browser, login to Gmail and they are automatically (gggrr) logged in to an instant messaging program within a browser! Searching the Google help forums I have been staggered to find that you can only disable chat/google talk at the domain level, so it's either on or off for everyone. If I disable it the students can't use the chat feature built in to Gmail (which is a good thing obviously...) but the staff can't use instant messaging.

After discussing with the staff we have decided that IM is too important a tool not to have for staff, and that the Google route is the obvious way to go. So we are sticking with leaving chat on, and putting the emphasis on the teachers to monitor usage in class, and try to educate the students about the appropriate time to be using things. It's been really interesting as what started out as a simple technical problem has lead on to discussions around a whole bigger issue of whether in these days of collaboration and communication, we should even be trying to restrict access to stuff anyway. I can see that the traditional role of the Network Manager is changing and even though I have always seen myself as an 'enabler' rather than a 'disabler' it is still a challenging time trying to find the right balance between giving students access to the tools that they need and use, but trying to ensure that they are used appropriately.....

Migrating email from SchoolZone to Gmail

In so many ways, the webmail component of Telecom SchoolZone is terrible. It's based on an outdated form of SquirrelMail I think, and my rollout of Google Apps at school is an attempt to replace it with something far better, Gmail. Google Apps comes with Gmail for all of our users, and they get to keep their existing email addresses. Switching to Gmail is a fairly straightforward process itself (that I'll talk about later I suppose) but trying to migrate users existing email and contacts is turning into a big job. SchoolZone email has no facility to export messages, so the method involves downloading a users emails into an Outlook pst (one folder at a time) and then uploading them using the Google Email Uploader tool. This in itself is a huge, time consuming job, but here Google falls down a bit too. The problem is that the email uploader tool doesn't support proxy authentication so fails through our school internet connection. Faced with these issues, I'm seriously thinking about not migrating messages at all, but giving the users shortcuts to SchoolZone email for their old email, and Google for their new stuff, at least for a while anyway. I can get them to forward any important messages in their own time and I'm comforting myself that it's a good opportunity to clean out some unwanted emails (even though they did this at the start of last year when my predecessor moved the school from Exchange to SchoolZone). It's ugly but easy, and will probably be all forgotten about in a few months anyway...

About the tagline

Google Apps implementation part 1

Welcome to my blog. Over the last few months I've been planning to roll-out Google Apps for Education at our school, and during the recent Christmas break, I've made a start. At the time of writing this, I've got Active Directory populating and synchronizing users and passwords with Google Apps (using the Google Directory Sync Tool). So far, I haven't publicized it to my end users (as they are all on holiday anyway...) and I haven't enabled Gmail as I need to do some more work on migrating from our existing email system. The only real gotcha that I came up against was synchronizing passwords. Active Directory stores it's passwords in binary, and the Sync tool can only read plain text, MD5 or SHA-1. To get around this, I've got this filter installed and configured on my DCs, which in turn populates an LDAP field with an SHA-1 password which is then read by the sync tool. The field doesn't get updated until the user's AD password is changed at least once, but after that it seems to work well. I haven't got Single Sign on going (and am not sure if I will try yet). So this next week it's the bit where I get to further explain to staff what Google Apps is, how it can benefit them, and how they can logon. Then it's implementing Gmail, and then rolling it out to the 800 or so girls at school
