I´ve read up on why the feature was rolled back, simply stating for discovery purposes. But wouldn´t it be better if we can choose whether we want the discovery or not.
We may not have enough students yet to start a whole another group. Run by a smaller team, its harder to keep two groups up and running. We want this one course to be a hidden course that is used by invited-only members.
Maybe an option where we can select whether the group is ´accessible by some members´, ´accessible at some level´, or just ´hidden´.
