Thanks for the update.
I've only been using the authoring tool since the start of the year and have been anticipating user management to let others in the team demo the system, without them altering my courses.
One question, if a user is permanently remove from the system, do their courses become orphaned? As a result of this, would it be possible in a future release to add another menu item under 'Shared coursed' called 'All courses', so even if a course isn't shared a user with enough permissions is able to access the course and maybe reassign it to someone else.
