Not that we can change them, but it's interesting to look at possibilities.
The only one that I have a problem with is this:
The spirit is right, but not the wording. It isn't possible to show the "utmost respect" without paralyzing yourself. Maybe "All posters should remember that they're adults and not children. Don't start trouble. Don't insult each other and don't try to provoke anyone into an outburst. Refrain from name calling, unjustified accusations etc. That goes for posts, PMs, or any other communication done through MERB."i) All posters are expected to show the utmost respect and courtesy in all communications. Refrain from name calling, unjustified accusations etc.
My version sounds harsher and less dignified, but actually it gives Merbites more leeway while laying down a bright line that people can't cross: Don't start anything.
Such is my view anyway. Anyone else's thoughts are welcome, whether the subject is this particular rule or any other.
