EVERYONE NEEDS TO REMEMBER THIS EVERYWHERE ON THESE BOARDS
Behavior on the site should be guided by a sense of common courtesy. Respect yourself and your fellow members. Avoid controversial subjects (politics, religion) and never post in anger. Flaming is strictly prohibited. If you have an issue with a fellow member, discuss it privately. If posted material is deemed inappropriate it may be deleted without warning. Explanations and apologies may or may not be forthcoming. Members are encouraged to keep an open mind, have a sense of humor, and accept that diversity of opinion is a good thing.
Personally I have no problems with things being discussed in public. Takes away any doubts about who said what in my eyes, but it must be kept civil.
Another good rule of thumb would be PG13 or less in the OPEN areas... Or don't post anything out there in the OPEN that you'd be embarrassed to have your Grandmother see... If you are about to raise a topic for discussion, or post a picture, and a little bell goes off in your head that causes you to wonder, "Does this cross the line?", assume that it does and desist. The rules are looser in the private areas but there are still limits.
