How come nobody ever FINISHES that old proverb about "don't criticize someone unless you walk a mile in his shoes?" It ends.... " that way, you'll have a mile head start on him, and you'll have his shoes, so he'll probably never catch you."

Seriously though. We all had to give an email address when we signed up right? The Admins have that information in case somebody gets totally out of hand and or the moderators can warn/ban them. That's what a forum is all about, people often disagree.
A word of caution. About two years ago, somebody said something on the SOS California forum which offended somebody. Thats the illegal immigration forum, Save Our State. Next thing he knew the FBI and Marshall's stormed in his house, ransacked the place, took all his guns and computer, and who knows what else. He was arrested, and his family didn't even know where he was for some time. He was arrested under the Patriot Act. I never saw what he said it was deleted, but you never know who's watching and who's trolling and I suspect he was set up because they were all pretty much decent people on there from what I saw over a few years.
I had to close down a forum I once had because somebody kept posting kiddie porn sites on it, and they were running a proxy, so every time I traced their IP it came out in a different country. I called the FBI, and they couldn't catch hum either. So I shut it down.
Personally, I try to never say anything that I wouldn't say in person. The truth is my sword.
