I agree with those rules, but I think that "hijacking" should be defined in some way. A post on the fifth page - assuming twenty-five posts per page - of a thread may have little or no bearing on the original post, even if it is completely in line with the direction the thread has taken.

I would also like to see "trolls" included in the First or Third line of your "basic rules" (using the Wikipedia definition of a Troll).

As for "guidelines," which I view as separate from rules...

I would also like to see a FAQ or "HOWTO" set up with specific information about conflict resolution (Either between two regular members or between a member and a Moderator), and how to report possible infractions (It took me a while to find that little flag icon).
