I'm pretty much just a lurker here, but I really enjoy the conversations. I do have some suggestions, taken from other forums that manage to remain polite even when dealing with emotionally charged topics.
Some of the key points are:
1) Please leave list management up to the moderators and management, rather than trying to jump in and run things yourself. If you have a problem or complaint about how the forum is run, or about the conduct of a member, the appropriate venue for it is a message to the moderators.
2) In order to keep this list a safe place for open discussion among our members, we ask all list members to behave with courtesy and civility toward others. Snark, sarcasm, and excessive flippancy are not appropriate.
3) Because of the diversity of this list, we ask that listmembers avoid stating their opinions as absolutes. We also request that you not claim that you (or anyone else) have access to universal truth.
4) Long screeds proclaiming the infallibility of some ideology or other, will be deleted; so will repeated attempts to hammer on a point already addressed; so will comments containing profanity, abusive language, flamebaiting and the like.
