The first two are universal nub threads, the last shows all the character forums. Don't just register and start asking questions and starting threads though (outside of the first link, you can post the simplest questions you want there because that's what it's for). SF4 brought alot of new people to the forums and the oldies are a little salty that the same questions get brought up everywhere. Those threads have helped, but theres still redundant clutter.
I can personally answer questions that might go under the radar over there or elicit mean responses too.
