An MHB Moderator is basically an MHB Site Helper who moderates a few forums. It is one rank above MHB Site Helper, and one rank below MHB Global Moderator. The username of an MHB Moderator appears in brown.
To become an MHB Moderator, you must be an MHB Site Helper as well as an MHB Math Helper or MHB Math Scholar. You must be nominated and seconded by existing staff. Although the MHB Administrators have the final say in who becomes an MHB Moderator, it is generally agreed that all existing staff from the MHB Moderator rank on up have input on who becomes an MHB Moderator. MHB Site Helpers together with MHB Moderators make up the junior staff.
