Merry, Nick, I respectfuly must disagree. This is still a great board with many wonderful people. It is great to see you back, BTW.
Yes, there have been some inexcusable, childish outburst as of late, but they should be treated in exactly the same manner a wise parent treats poor behavior in their children at home--Rule #1 of raising children.
Praise the good behavior and ignore the bad.
It works for big children just as well as little ones.
