Well, my statements were somewhat harsh, but I really think that it's useless to go through detailed bureaucratic procedures in this sort of environment... It soon become endless quibbles about very minor points, and noone read them, and much less respect them
So OK for a *short* PBW etiquette document listing "proper behavior" though, as an help for newbies. More than that should be left to Game Masters if they want specific rules.
And frankly all relies on the individuals'goodwill, no amount of rules will change that as long as there are no retaliation other than just kicking out the players from a game.
If the "rules" just listed and informed players beforehand of what can lead to their banning from a game I think the goal will be attained.
