Manual
Published sites are available to all site participants and appear in their site tabs and lists.
Unpublished
If the site is left as draft, or unpublished, only instructors/site owners may access it and students will not see the site in their list of sites. Throughout the site, instructors will see the Unpublished Site banner and can use the Publish Now button to quickly publish a site, without going through Site Info.
Confirm Site Visibility.
In most cases, site owners keep the default value for Global Access "Site participants only". This will restrict enrollment to people that you add manually or that are enrolled automatically from your institution's registration system.
If the site is set to Display in Site Browser (as shown above), anyone in your system may search for your site.
