Is there a way to create a usergroup for donors etc..., independent of post count?
Yes, just create a new usergroup... or is there more to this??
Oops
I meant
User Title (Newbie, Junior Member etc).
Then no, unless you put them in a usergroup that has a different user title and not allow them to change it, I don't think you can.
You can change them on a per user base too.
