The Office Director was a former position in charge of making sure that the Office was cleaned, and they always took priority over the comfy "Commander" chair. This position is now defunct, as is the chair, which disappeared at the beginning of the 2009-10 school year.
2010-11 and Beyond
As with many other positions old and new, the Office Director has been made a position for the 2010-11 year, albeit with a new name. The Officemaster will have the same duties as the former position of the same name. However, the power to kick people out of the office is solely an ability possessed by Commanders.
