How do you get a list with all the permissions on the world? Cause i wanna add specific ones to specific groups! PLEASE HELP
You go to the plugins page, and 99% of the time they'll have the permission nodes right there, or on a website. For example, the Essentials nodes are located at http://wiki.ess3.net/wiki/Command_Reference/Perm
They have a development release for it for 1.5, but I wouldn't recommend it considering they said only use it for testing. I am using PermissionsEx right now, and just got mine all configured.
Permissions plugins aren't something that should break between updates. There are plenty of permission plugins that still work.
