So, you feel emo enough to run away and delete your account? Here's what you should do:
1/ PM an admin and tell him/her that you want to delete your account.
2/ The admin replies with a confirmation, telling you, in essence, that after exactly a week, you need to contact the staff again and confirm that you want to go through with this cowardly act.
3/ After one week, you need to contact the staff and confirm your intention to leave us.
4/ After receiving your confirmation, your account is deleted by the staff.
You can stop this from happening at any time, while you're still a member, simply by pretending that you never sent that PM in the first place. A monetary gratuity will help, too. That last thing is a joke.
Should you want to register again, you're obviously free to do so, but your post count and karma belong to the deleted account and cannot be retrieved. Sorry. Not.
