This is an issue related to setting up a workspace with several projects for teaching, as I did here:
Collaborators can work on a temporary version of a project, but if they make a permanent copy it seems to get added to the workspace. As the default number of projects on a workspace seems to be 5, the workspace quickly fills up and collaborators cannot make permanent copies any more.
Is there a way they can make a permanent copy to their own workspace? Or is this just a bad setup and I should be doing something else?
