is it possible to change your user name, or get someone to change it for you? I really don't like my user name, and I would really really like to change it
Yes it is able, but I don't know if the admins want to do it. It has been done a few times before though.
As milanos said plus you should pm one of the admins and ask if it is possible for you to change your username. But don't be disappointed if they say no to your request.
