Other thing how do you get that thing under your name and how do you get a avatar
If you mean 'citizen' or what-have-you then it's generally either by post count or winning some sort of forum game. If you mean in-game then you can get them by finding 'badges'. If you go to the collections menu you should be able to select one of the ones you've found.
You need to be a VIP to have an avatar.
