Now, as you can see, a simple field with either "Licensed" or "Associate". There shouldn't be any reason why these cannot be displayed. If you are trusting enough to have someone listed as an Associate, you shouldn't have an issue if others know they are on your license as well.
Now, their is a link for the titles, that will display an overlay when viewed from the postbit:
Again, the license holder should be listed first, and possibly have something that identifies they are the ones with the license. Since you are allowed up to 4 names, I just used the max and went with it. For each of those names, they will have the "Associate" title listed under their name and before their user-title.
If a member has yet to purchase a license, or has had theirs revoked, nothing will be displayed. Pretty simple.
Of course, this can be expanded to the member card, with it in the same location, as well as having a tab or block on their profile page.
Obviously, that link would have to go to the members profile page (if in a block) or to the Member Association tab.
*Note - All members listed here have a xF License. I just felt they were the least likely to moan about having their images used.
