When Jim left for TX (August?) I expanded the powers of the sidebar moderator to include the new ability to suspend accounts, and the ability to remove comments and articles. As well as the sidebar duties. I created a higher level moderator function for banning and especially nuking, this was called "admin moderator". And I created one special class of moderator now called "lead moderator"; this person, and there is only one, is basically the foreman, and has access to the moderator logs and their names. (Moderators are anonymous even to each other.)
