Admins and Chat Moderators

Users become admins too early these months,users before 100 edits become a chat moderator,users become admins before 350 edits. For now on,I need to make a rule,if you have 300 edits and more,you can be a chat moderator,if you have at least 600 edits and more,you can be a admin,but before you become a admin,admins will have to decide.
