Chess websites

Name a few good ones. Preferably a site that keeps track of your rating, correspondance or real time, I care not. No Yahoo chess, though, the place is wierd. Also no gameknot, I have an account there, and I played it a year ago, but it has a really low rating, and I'm better now, but don't want to have to crush a ton of weak players to play on the level I am at now.
