just thoughts for how things can flow easily here.
take a couple different types of mods. take a younger one, avg board age and a little older person. give them Mod privileges for a limited time. if they perform well and do things as you think they should be, then extend them. if not, thank them and find a new person.
any bans should be agreed to by all 3 mods. IP bans are only to be carried out by the you and Hurl and all 3 mods. WARNINGS can be levied by any of the MOds or admins.
that gives accountability----- just social structure ideas.
