Sorry not sure if this belongs here but is there any way to change your user name or do you have to create a whole new account? Thanks
You can't do either I'm afraid, creating a new account will get both the new account and the old account banned (they match up on your IP address) and you can't change your name unless you PM someone with a red name and ask, and they'll say no. Sorry
You can't change it yourself. Only administrators (users with red names) can change your user name, and only if you have a good reason. You could nicely ask one of them, and they might let you change it.

You can't create another account. If you do, we'll find out and ban the new one permanently, and give this one a regular ban.
