Anyone know any good Online Raid tools?

The one we've been using pre-Wotlk hasnt updated yet for wrath content(doesnt have DK class, and no listings for Eye and OS)

Do you guys know of any good online raid tools were you can post dates, and people can sign up for raid slots? The ingame calendar is ok for setting dates, but figuring out raid composition is kind of a drag when you got 5 extra people logging in waiting for a slot. (not thats a bad thing all the time)

Something like http://raidcomp.mmo-champion.com/ ? Or www.raidar.com can work either, in just a different was where people sign up and such, now thinking about it, the MMO-Champion one just lets ya sort classes/specs,not actual players :/

Group Calendar works pretty well for this. It is one extra addon but it has some extra functionality on top of the blizzard calendar.
