When a faction admin is kicked from his faction for whatever reason (not logging in for too long, a server admin running the /f kick command on him, the player being banned from server), another player will now be promoted to faction admin in his place. If the faction has at least one moderator, one of them will be chosen. Otherwise, a normal member will be promoted. If the faction admin was the last/only member, the faction will of course be disbanded.
