Here's what it says in the FAQ with regard to username changes:

"How can I change my username?"

"Members can change their username once and only once with no explanation or special permission needed. Simply send a private message (PM) to one of the site's administrators (not DocJohn). Member names have to conform to our community guidelines, be between 4 and 19 characters in length, and not already taken by an existing user. We allow only one username change per individual."

Here's a link to the citation:

You can change your title by going to "Edit Your Details" under "Your Profile" at the top of the "Your Control Panel" listing on the left-hand side of your "My Profile" page. At the top of the second box down on the "Edit Your Details" page is a box that says: "Custom User Title". That's where you can change your default title to whatever you wish to use. (You'll notice mine is: "Apparition". Hope that helps...
