keep away unwanted conversation for example one chat room is dedicated to talking about this or that and there should be one big general chat for example we don't want SSBB conversations stuffed in with people who hate that game (this happened for real).
This isn't gonna happen unless the chat room starts getting REALLY busy. There are rarely more than 5 people in chat, and I don't think I've ever seen more than 12 people at once. So there's no need to split it into channels of even less people.
