Email support and ask for a change...dont do anything stupid like opening another account..as somewhere down the line when you get 100K in the account they will decide to close th enew one and keep your money
If they wont allow you to change the name, just keep it and worry about playing winning poker, not the name you have
yea email support because sometimes they do checks and if you create mulitple accounts they will close all your other accounts and if you have money in them you lose it. and they will make you go back to your orginal account
