Group Manager

GroupManager is a plug-in for Spigot/Bukkit based Minecraft servers. It facilitates the grouping of permissions to​ assign to players. Each group can have a full inheritance tree of other sub-groups, enabling players to have differing levels of authority and control with a promotion and demotion hierarchy.

GroupManager has an extensive world mirroring system that allows you to tailor your permission assignments​ for each world and span permissions across worlds. It now even supports time-limited permissions.
