You go onto the job boards like Monster and look for non-paying openings for a moderator. These generally don't require experience. You should also be familiar with internet Laws and basic TOS (Terms of Service) agreements, these are generally pretty standard across the board so reading one or two from any sites will give you a grasp on what most companies have. Also read the COPPA act and familiarize yourself on what it is and why and why most companies simply choose to not allow those under 13. Most paying Moderator jobs require experience so nearly ALL Moderators start out as volunteers.
