Not a good idea at all. It never works. I do have, as ever, a horror story about this sort of thing but I won't bore you with that now. The problem with a mod/admin that is elected by a poll of the userbase is as follows:

1) The userbase elect a personality, not someone that is is best suited to the job.
2) Most of the userbase won't bother to vote, only those that are trying to push their particular candidate.
3) Once in position the person may feel somehow beholden to those that elected him.
4) Encourages the formation of partisan groups, leading to flame wars and boycotts etc.
5) The person may lack the required skills.
6) He may dissolve the admins and mods and proclaim himself emperor of all the org
7) Camels might get deleted.

If this were to happen we would be looking back on it years later talking of the "Golden Age" of TosaInu and the folly of the fools that thought they knew better:

AndresTheCunning: "...we believed we knew better, but now, under that most despicably evil tyrant, Caravel everything is illegal. It is eternally black and none are happy. I remember the avatars...

New Member: "the avatars? surely they are a legend like the signatures?"

AndresTheCunning: "no, they existed once, and there were signatures, and colours, and the moderators kept the peace, all were content and camels ran freely upon the open forums... all gone now..."
