IIRC, there is no way to delete your account. The staff keeps a record of all members who have joined for reference. It is possible to have your account deactivated of course, though you will have to PM an administrator and work it out with them; deactivation is analogous to a ban and is handled the same way, and thus administrators are the only ones with the access permissions to effectively deactivate accounts.

Why do you want to have your account deleted?

If you don't like your current username, you can request to have your username changed.
You may request to have your account disabled by PM.
Note: Disabled users will not be able to create a second account until the disabled account(s) gets pruned/deleted automatically which is every 365 days.
