There are two types of users in Spotlight: Administrators (admins) and Curators. 

Admins will see everything in the Configuration and Curation Zones. Curators can only see the menu under Curation.

To add a new user to your exhibit, go to Dashboard > Users>  Add new user

Enter the email address of your new user and decide what privileges the user will have by selecting an appropriate user "Role." 

Remember: an "Admin" has access to both the Configuration zone and the Curation zone and can delete the exhibit. We recommend that you make most members of your team "Curators," because "Admins" can delete items as well as the exhibit as a whole.
