Q. Can I change my username?
A. Yes, this option is available to all Platinum members who have been registered for at least six months and have at least 50 posts. You can change your username once every four months. It can be done here. A name change can be denied if the username contains profanity, special symbols and/or characters, or is being used in a way to harass or mock another poster.
