Just for future reference, requests for accounts to be closed always have to come to me in a PM ("conversation").
Also, XenForo doesn't have a real 'account deletion' sort of thing. I can use the spam cleaner and get rid of all your posts if you haven't been here long. The 'delete user' on my side basically just removes your avatar and bans the account. In the past, I have just put bans on the accounts requesting deletion with a special note that it was user requested and the ban can be lifted in the future.
