Thanks muskrat, I often feel the same, though there are sometimes
valid enough reasons to delete your account. Most of the time it's a knee-jerk reaction to something however, and a day's distance is often enough to allow a more reasonable approach.
The correct process for having your account deleted is to PM myself
or one of the other staff. (Though it is faster to PM me directly.) The process is that I will try to talk you out of it, but if you are certain, I will remove the account. The issue is that when an account goes, often a good chunk of information here on the forums goes along with it. In order to help preserve that history, we try to avoid deleting accounts, as often there are better ways (E.G. changing your account name, hiding personal info, removing specific unwanted posts, etc.)
One more admin note: Once an account is deleted, it is gone for good, and cannot be recovered. Furthermore, future registrations, even under a different nom de guerre, will not work, so please... don't take the decision lightly, make sure it's what you really want. We've already had a number of people change their minds after the sun has risen on their original decision to leave.
