Pages or individual boxes on a guide can be hidden from view and then have visibility toggled on. Example:
The attendee poll for this session was kept hidden until an hour before the session just in case someone stumbled across the page too soon.
Guide editors are allowed to create and edit content on the guide and change the guide properties, except for the Guide Status.
A librarian can create a shell or template for a guide and then grant the course instructor editing privileges for that specific guide.
A course assignment can be structured to have the students search for potential resources on their topics of interest. Grant editor privileges to each of the students so that they can build the content themselves.
