It does work on individuals, I've done it before, you just edit the config.yml thing I think. I had it on my friend's server where we each had unique tags.
EDIT:
Here is how you do it if you want to know, the example is crashpunk's since he is mod or whatever.
users:
wariopunk:
group:
- mod
prefix: '&9Server Moderator &f- '
You can use that if you wanted but you'd have to change the "- mod" part to the name of the class you want them to be in, because of course, I don't know what you've named the groups.
That one would make the server moderator bit the blue-ish colour crash's name is in right now and it would make his actual username white.
Exaple text:
<
Server Moderator - Wariopunk>
Donators could be something like:
users:
exampledonator:
group:
- regulars
prefix: '&6Donator &f- '
That one would do this on chat:
<
Donator - exampledonator> Hello!
Hope that helps.
By the way, it's the permissions.yml file not config.yml.
