If you really want your account deleted, you can contact any administrator to have them do that. Carlie is one of them. But really, why would you want to do such a thing? If you really don't want to come here anymore, why not just leave the account inactive? That way, if you choose to come back another time, you still have your account waiting for you.
As Freakenstein said. It is often hard to get the account deleted, because that is not something Carlie would normally do on request (hence people being idiots and flaming, spamming and posting porn to get the attention of the mods, just to get the permaban). Instead it is simply recommended you close your comments (control panel > disable comments), and just leave. Disable notifications too, if those are enabled, and you won't hear a peep. If you really want to get off the site, you can even open notepad, mash your keyboard, and copy that into the "change password" field. Change the password, delete the file, and log out. Voila.
