I posted a feature request: http://bugs.bukkit.org/issues/169 For now, it looks like we will have to implement our own systems. Here is my take: https://github.com/jsedlak/Kikkit/blob/bukkit-conversion/src/SecurityManager.java Requires groups.txt Code: # groupName:/commands,/separated,/bycomma # * denotes all commands admins:* mods:/kick,/ban vips:/home,/sethome And players.txt Code: # playerName:groupName Kr1sc:admins lordenix:admins someUser:mods The functionality is that groups have access to commands, and players are in groups. My code doesn't feature group inheritance, and doesn't support chat coloring. Nor does it support adding players at runtime. And it hasn't been tested (I just finished the conversion to Bukkit). Feel free to use, improve, et cetera. Hope this helps! Edit: Fixed some bugs.
