On the right, just above the start of a thread you'll see your user name listed along with those also viewing the thread/board, click on it. Then go the bottom of the menu on the left and click "delete account." it's that simple. 
This seems like only a temporary fix, looking for something more permanent.
Delete acct, then pour Dr. Pepper all over your lap top.
If the former doesn't stick, the latter will.
