I configured the xperms permission files like it said in the wiki but the prefix wont show up. Basically what I need is:
[Chat-Mod]JimmyTimmy but what i get is just
JimmyTimmy. JimmyTimmy has all chatmod commands but no rank in front of his chat name. Here is my config for default(none would show up).
So what did i do wrong. Do tell.
