I have used private categories with “less private” subcategories, so that a group can work in their space and publish things to a larger public. I guess this line of work will become obsolete by this change. So I should let users know that when they want to publish something, they need to move it to another, more public category. But then, how do they find their common work on this? I suppose they need to maintain a “publications” topic where they link the ‘more public’ topics. Any thoughts?
