I started participating on three of the very first conferencing systems in the country in 1984; at different points I was "promoted" to various levels of administration, finally being among the very few granted root access. There were always all kinds of people bucking for promotions to the system - be it fairwitness to a conference, or conference administrator, user administrator, or root itself - one of the things I learned early on was NEVER to give that kind of power to anyone who asked for it or even hinted they wanted it. They almost invariably wanted it for the wrong reasons. It sounds weird to say, but that kind of thing is better being thrust upon someone who doesn't really want it. If I were appointing moderators to a forum, I would probably apply some of the same logic.
