How necessary is a TOS?
RiderOfGiraffes: Personal opinion, based on limited experience.Essential, unless you want to endure endless complaints about there being no rules, so how can they be banned because they didn't do anything wrong, because nothing's wrong because there are no rules.Be blunt.  Say that people are expected to behave well, and that if you think they aren't behaving well then they'll get one warning, then be thrown off.Make it clear that you are a benevolent dictator.
