Well, I personally think it would be more polite if it were limited to moderators and not regular members.
The problem with this is that when a mod makes the comments, it has a smackdown feeling to it. Sometimes a smack is what's needed, and sometimes the give-and-take of the forum community is more effective. It depends on the situation. Often I check out a report, see the offending post, see that one or more members have addressed the issue well, and because of that, say nothing myself. This is especially true if the members addressing the issue are well-respected.
Ehell is never going to be a place where there is a itty bitty rule for every itty bitty situation. Members are expected to use their judgment.
With respect to you and cass2591, I've never seen the phrase used as anything but
And it's one thing for posters to disagree with each other and say so, but I try to deal with it by suggesting agreement to disagree or something like that-it doesn't come off as a smack. For non-moderators to deliver smacks doesn't strike me as "using their judgment" but as being snotty and sometimes even bullying. I've never seen snottiness by non-moderators accomplish anything in any
situation except hostility, hurt feelings, alienation from each other, and sometimes even retaliation. Our forum has split several times before, and I think lack of a policy on this has been part of the cause.
I truly believe that only moderators should deliver smacks-not fellow members. Presumably moderators have been selected because they do have reputations for good judgment, know the ropes of the forum, and don't bully others or act as though their feelings don't count. This is not necessarily the case for other members of the forum.
