When you enter the chatroom there are different colors:
Green = Guest (which is what you will be when you first enter the chatroom, it only allows you to PM people in the chat)
Blue = Member (which you have to ask a moderator to Member you to attain. It also allows you to talk in General chat with everyone else)
Moderator = White (these are the people who have the power to bump you status from guest to member, we also can kick/Ban for a good span of time)
Administrator = Orange (They own the chatroom and consist of Evewasframed, Minus and Steel. If someone misbehaves enough they can permaban them from the chatroom)
I hope this helps
