I must learn more about Wiki's - it's not something I've been inclined particularly to look at in any great depth, but they are a great way to collaborate and share information about just about anything. Having just found a Wiki on Group Policy, it had to be worth blogging. It can be found at http://grouppolicy.editme.com or alternatively through http://www.grouppolicywiki.com. There's loads of great information up there. Don't also forget www.gpanswers.com, another great resource.
