Also, rating. Like, PG or G or PG13 or R or anything in between? I think that would help since a lot of young people (including me) want to keep their innocence. It would also help for what people choose what to respond in the chat forum. And also, maybe there should be a "Kick" or "Unkick" option for the people who have made the thread so if someone is being abusive on the chat then they can simply boot the user out. It would be a good thing to put on all chat forums, actually. Sorry if my ideas are stupid, you don't have to take my advice, I'm just putting it out there as a suggestion and nothing more.
I think that the kick or a kind of uninvited button would be good..and if you were inviting someone into an rp you could just click a button or something like that..ratings would be good too
