After creating a Content Object, all students (Users) will have access to it unless restrictions are made. Access Control allows the site administrator to control which users, groups, or roles can view the Content Object.
If you'd like all Users in the site to view the content, then you do not need to edit the Access Control settings.
If you have assigned a Content Object to be released at a future date through Availability Settings, applied an Access Control that does not include you, or assigned a Dependent Release, the Content Object will be grayed out in the Administrator's view. The student(s) will NOT see the Object until all criteria are met. View the Permissions Summary to see a report of all permissions applied to a content object.
