Hmm, I thought this newer version of UBB automatically changed the number of "edited by" messages to 1?
Doesn't matter, there are things to say in favour of it and things that aren't. Let's just hope we won't be confronted with any negative consequences, as in troublemakers yelling something and then changing it after a few indignant replies, claiming he never said it. And pretty hard to find out if he edited his message or not. Oh well.
