My secret is to have as few rules as possible and only have enough rules that allow for the effective running of the room - but NOT undue control over people. Personally I don't care about excessive caps, colours, bold and other similar petty rules. If these things bother people then they need to find some more variety in their lives.
If you spend too much time ramming rules down people's throats then they will simply spend more time on working out ways of breaking them.
