As mentioned above, once you send a request to have your account deleted, (note that this will be permanent) you will have to wait a short while until a Staff member can approve of the account deletion.
You have how long I be waiting for this approval? At time when I left for two years, my account wasn't deleted. :/ Can you do it?
As Red answered on your own thread about this subject:
Most of this matter is the server since the Admins rarely deletes accounts nor can we delete accounts on Request. Forum users may deactivate their forum account but the game one will remain until it has been inactive for years. Raz is really the one that works the most with the accounts on the server, but not much work is done directly with deleting accounts since the only one/thing that really does this is the server itself.
Hope this explains it somewhat.
Locking this since it has been answered.
