A while back Rohan, from Blessing of Kings, started the Raider101 Wiki. I don’t think I’ve mentioned it here but I’ve found it extremely helpful to me when I’m playing an alt.. or when trying to help a guildie who plays a class I don’t.
I wrote most of the Affliction Warlock wiki and will update (and simplify) it somewhat after patch 3.1 is released. But this is a huge and fantastic resource.

The important part is to keep things simple. The intended audience is not the people who can do 3000 DPS and are trying for 3500. The intended audience are the people struggling at 1000 DPS. After they master the basics, they can go to Elitist Jerks and delve into the deep theorycraft.
The resource has grown to also include pages for healers and tanks. Go, have a look and if you see something that needs an update, add a comment or update it.
At the very least, keep this in mind and share it around. It’s a fantastic resource.
