In know in 4.X the ability to create Groups in Projects was added. Is there a way to restrict users so they can ONLY create projects in Groups? Additionally, it would be preferable if only the Group Admin could create projects wihin that group.
The way we have configured our system would dictate these requirements. Otherwise this may confuse our users.
If you take away the create project permission for all spaces, then that should work for you. It might be a little bit tedious, but should work out of the box.
