We have been having some problems with bots trying to spam the board.
If you have tried to create an account, but it has disappeared, likely your account was flagged and deleted because it fit the parameters of a bot. Generally, this happens when your username or e-mail address is a mix of random letters or has large, undefined numbers in it. This is especially true for free e-mail accounts like gmail, live, etc.
If you find that you are having trouble getting your account to register, please send an e-mail to email@example.com and we'll get it sorted for you.
