All moderators must be at least twenty-one years of age. No user may be considered for the position of moderator unless the user is twenty-one years of age or older. Got ID?
There is no real "age restriction" for moderators. Generally, moderators should be matured, around sixteen or so. That doesn't really matter, however, given that forum moderators don't apply for the position, nor do the forums administrators check for qualification. Administrators appoint moderators based solely on their attitude and reliability. Basically, be a rule-abiding, social, and friendly user, and..who knows!
