Consider the following scenario:
A user has two roles assigned: Subscriber and Supporter (with the latter being of higher priority)
In settings, subscribers are set to correspond to green color and not to have a user badge showing. But Supporters are set to show user badge and be colored in pink.
In this scenario, an expected behavior would be for the comments of that user to have a pink Supporter badge. But what actually happens is that the user is still treated as a Subscriber - they are green without any badge.
I temporarily changed my site to switch user roles instead of adding a new role, so it isn't anything problematic for me, but I wanted to let you guys know because there might be others who have a real need for multiple roles per user.
Remiel,
I'm really sorry, but it'd be too hard to detect the role with high priority. wpDiscuz always gets the first user role.
