I am attempting to clean out the 13k fake auto-registered members that got into my site before i disabled registration... Given that there are so many, I am looking for a way to just wipe out all members who registered, but never posted.

I tried to set my viewing to a large number so I could do lots at once, but the code seems to 'hang' if I try to do more than about 100 at a time.... way to slow considering I have 13k to get rid of.

anyone have a good tool to wipe out all 0 post members in one shot and clean up the Members files without losing the few real Members profiles?
