You're going to be reading the posts and trying to read them as someone who doesn't really the personality of the poster. That way you will see something that sounds argumentative, adversarial, inappropriate, etc... much easier. I think if I'd remember to read them that way I would be less likely to miss a post that could start an argument or be taken the wrong way. If you wouldn't mind you child (figuratively speaking) or mom read a post, it's probably ok. If in doubt you can put a post or thread into moderation. There is a whole thread about how to do this. If you do put something in moderation, send the poster a pm explaining why. You can always ask this group, but if you feel strongly and there's none of us on site, just kick it to moderation. Sometimes the poster doesn't take kindly to your actions - just don't take it personally. Problem posts run in spurts. There were just a run of them, so it may be awhile until the next group. Hope that helps.
