I'm using both the latest versions of CB (1.9) and GJ (2.7.0), but when I go to the CB User manager, there is no "Join GJ Group" button to the left of my "New" button. In fact, it's not anywhere on the toolbar. Yikes! I am using J! 3.11 if that makes a difference.
I can't see any way to add my users into their respective groups...
