Rob spends his life on the internet and just views the message board and constantly refreshes, therefore he is able to read every single post that is posted and immediately deletes inappropraite ones :-) Rob and I both have the power to delete posts, I usually leave it to rob unless he's out of town or I happen to stumble onto something completely out of line. There's not too big of a problem on this site simply because of the fact that it won't be tolerated. If something is out of line, it gets deleted, plain and simple. Sometimes an argument is left to stand if there's relevant info or it's under control or whatever, but if there's anything inappropriate it'll get the can.
