If this setting is configured as Public, users from the Internet will be able to register a new account with your instance of Curatr and gain access to the homepage.
This setting being checked 'on' is desirable where you are looking to attract new registrations from any outside participants, or if you are selling access to a Curatr course. However, it is generally not required when organisations are using Curatr internally.
Note: Just because your Curatr is set to visible, doesn’t automatically give users the right to view each course within your organisation. On a course-by-course basis, you can elect to allow users to self-enrol to the course, or to deny this privilege.
