The site has almost 13,000 members. Today around 160 were online, many with multiple posts. How would you go about regulating all of that? We can't make people get along and play nice as it's an open forum. When things get out of hand the staff will generally chime in. Sometimes threads get moved to QT as that's what it's there for. To think that this many members will not rub each the wrong way from time to time is wishful thinking.
Everyone should have the ability here to voice their opinions. When those opinions don't match your own that makes for a discussion. That what forums are all about.
