I am writing server texts for a different server and I found myself at a loss when explaining (in book form) the differences, advantages, and weaknesses of each school of magic. If I could get a link, or a DM with enough time on his hands could write down a description of each school of magic, I would be grateful. ((This project also explains my lack of presence online, and the sooner I am done the sooner I can get back to trolling you all.))

They're all detailed in plenty of other places, Thomas the Younger!

NWN has short descriptions, as do plenty of the core D&D rulebooks.
