Please, please, please can you introduce an option to disable users from sharing their own copies of workspaces.
Even if a user does not have permission to "create" workspaces, as soon as a user has access to workspace, and have a workspace shared with them they can:
change the set up of the workspace (within the limits of how it has been curated)
save a copy
share this copy with everyone in our organisation
This is proving to be a nightmare to manage from our point of view.
I don't mind the users being able to tweak and save their own copies. It's just when they start distributing their own (often sub-standard or conflicting) versions with everyone else that it causes some major headaches !
I only want "Approved" versions created by people who know what they are doing to be available for others to see - hope this makes sense?
