The following access privileges are available in the portal:
Admin allows users or groups full administrative control of this object, including deleting the object or approving it for migration.
Notes:
The Everyone group (all users) has mandatory Read access to authentication sources, content types, filters, invitations, and properties.
Header and footer portlets used in a community can be seen by any user that has at least Read access to the community.
Access privileges are based on the security of the folder in which the object is stored. Changes to the security of a folder apply to all the objects within that folder. If one of the documents in the folder is shared with another folder (such as when a document is copied from one folder to another), the security of the document is changed in both locations.
