Id like to give the Admin and the Users prefixes in their name, like [ADMIN]. I entered a prefix in the permissions.yml but it isn't displayed?!? Running CB1.3.1R2.0 on Win 7 32Bit and Java6, Server is online mode TRUE, is it caused by the plugin NameChanger or do I have to give them a prefix permission?
You need to have a chat plugin. The chat plugin puts these prefixes and suffixes into effect. I recommend mChat.
