A more customizable moderator permission system.
A better forum permission system.
A better moderating team system. One that lets you put members into groups, instead of all people with any amount of admin access showing up as admins and anyone who is a moderator showing up as a mod.
A MODERATOR CP. For approving posts, reading reported posts and managing infractions.
And a better warn system. One that lets mods only give a warning, not an infraction, set a warn amount, so minor advertising and insulting members are not on the same level, and such.
