From the rules
When making your account name, take the time to think about what you want to be known as. We will not change your name later if you request it. So, pick your name wisely. Donít make a new account later for a new name, as we ban new accounts we catch for that. So take some time, and really consider the name you choose. Avoid fad concepts, as in a year or so youíll hate the name. Trust us, we get a couple dozen change name requests per week, and we give them all the same answer.. no!
