I just know thast once you obtain X number of points, (I'm sure it is explained somewhere), that you have the opportunity to remove messages. I believe the points are obtained through participation, but I could be wrong. All I know is mine go up and down, as well my 'position' changes almost daily. Not that it is important, just an observation.
If anyone that doesn't have the required # of points to remove a message wishes a message of theirs removed in hindsite, just ask.
I'd be glad to oblige.
I would hope it not be necessary for anyone to have to remove posts in the future.
