I've had 3 extra answers zapped overnight mollykins, Ed took off someone last night and as ummm says, if it was a prolific poster, it's easier to zap the lot rather than Ed having to pick 'em off by hand.
I supose so, and if the question is a little bit dodgy and then the answer get worse and worse, with no sign of a civilised, sensible answer he/she would just get rid of the whole lot, meaning everyone would get a question/answers removed.
