I'm good with doing away with the separation between ORG and Live but your suggestion does have some merit. However, there are people that have been here less than a year and have thousands of posts. There are others that have been here multiple years and have yet to crack a hundred. Some of those 'longtime readers, first time poster' types understand the culture quite well 'cause they lurk here everyday; others only occassionally and don't necessarily have a feel for the board.
Some people have been banned here and it had nothing to do with points, posts or longevity. To my recollection, the people that I'm aware of that have been banned have all qualified in terms of all three criteria----but I could be wrong about that. Simply continue, warn, suspend progessively for problem posters and, finally, ban as a last repost. (Redszone would sort of become the NFL of baseball boards.
