Minecraft – How to hide the plugin list from the users

I'm not sure if you still have this issue, but bukkit has removed wildcard support on permissions.

Bukkit has an in house permissions engine, but needs a plugin to tell it which users have which permissions. The in house permissions engine does not support wildcards and it doesn't matter which permissions plugin you have installed.

Learn to use parent/child permissions and groups.

Read http://forums.bukkit.org/threads/permissions-faq.25080/ for more details, it is under the "for everyone" spoiler.

There is the sub-group "worlds:". This most likely governs what the group can do in said world. Try typing the name of the nether file (by default it is world_nether) in the format shown with "creative". Then add the node "permission.build: true" along with anything you would allow them to do in the nether.

Sorry if this does not work as I used a different permissions plugin in my limited server hosting days.
