Applying to be a PickaxeMania Staff member does NOT mean that you will become a staff member. It simply expresses your desire to be a Staff Member.
Applications are kept on file and reviewed as Staff Positions open up. When this happens, if you are an active player at that time, your application will be considered, regardless when you applied. This means that even if you don't get selected when Staff Positions open up the next ground, you will still be considered during subsequent open position opportunities as long as you are active.
