Any way I can change my forum name without creating an entire new account?
yes. send your request via an email from the email account you registered under to
[email protected] and they will change your user name. (Indicating your current user name and requested new user name.)
From your thread title, I thought you might have wanted to change the forum name from "Genereal Chit-Chat" to "Ghost-town" since that's what this section has become.
