Now that all the responses that don't help are out of the way, i'll give a try.
I'm not a mod, so i'm guessing, but it doesn't say 'banned' under your name. I'm thinking that maybe that means its not a perma-ban, but just a temp ban. I believe they have 10-day bans and full bans. Hopefully, though, a mod will step in and give you a more solid answer. Also, does it say specifically that you've been banned? Or just trouble getting in the room? Occasionally it can take me up to 10 tries to get in.
Anyways, good luck.
