Still thinking... but greg had a good point about board moderators.
My idea goes back to trying to prevent the problem from developing in the first place. You know how it goes, first the snide little remarks towards someone. That someone takes offense and snipes back. It continues to escalate until anger is in control and reason it out the window. The person to catch it first is the board moderator.
So my suggestion is two fold. 1) train the moderators. As you know it isn't easy to moderator a board. Maybe there could be a help section that gives examples of posts that are focused on the poster vs. posts that are focused on the stock and it's issues. 2) Nip it in the bud. When snide remarks and sniping starts, deal with it right away. Address it right away while it's a minor problem. At this point, your more likely to make a gentle suggestion about posting style and rules and have it accepted. The boards I see that rarely have problems take care of problem posters right away. It's just like kids (not to be condenscending, but to demonstrate human behavior)... if you let them know their behavior is unacceptable right from the get go, at the smallest offense, they learn quickly where the limits are.
It's late and I'm rambling... food for thought...
darn... now all I can think about is a KKD chocolate iced... and they are open all night...
