Thanks Kirby,
Duh to me

lol.. I had forgotten about that.. How about something like this?
If a user registered 45 days ago, and is still awaiting email confirmation, and has 0 posts, the 46th day, their account will be deleted. This should solve the problem of having accidentally deleted 'normal' users who might have merely changed their e-mail address where we can manually find out what their problem is. This would cause only those new members (who I don't allow to post while awaiting confirmation) with 0 posts to be eliminated from my database.
Is a query like this possible?
