Thanks for the feedback. Our goal of 10.0 was to release a version of group boards that serves the needs of large organizations. So we built the feature with multiple group boards in mind. We are considering bringing a version of group boards to CE as many of our users are telling us it makes sense for smaller organizations as well.
