Hey Andy,
Thanks for putting it up on the forums; I'm gonna try and find some time to continue to work on the article, adding what people were saying in that forum thread too. Sorry I haven't been too active the last few days and I won't be for a few weeks because of how close my exams are getting, but I'll try and be on from time to time to keep helping out and editing where possible. Exams finish in mid-June so I'll be back to normal then.
David
