My GM has made it so only he and the two Co-GM's can post in the CS tab, and we only adjust it to show who's the current players. We don't remove them from the OOC tab, so people can still read them there, but it does make it a bit easier to work out who's on what team (because it's two teams of four, plus NPC teams). Probably not the best way to do it, but it helps us keep it organised.
