 site roles the following roles have been created to give an overview of how roles can be used to create different levels of access and a different look and feel to the site anonymous user this role refers to people who visit the site but are not site members people who have not signed up for an account audio users in this role can create podcasts authenticated user the default role for all site members users in this role have a blog and can store bookmarks create groups create image galleries and portfolio artifacts instructor instructors have all the rights of students but can create courses and assignments maintainer site maintainers have full rights over editing all site content siteadmin the siteadmin has full administrative rights over the entire site this role should be used sparingly student this is a placeholder role for added security all rights can be removed from the authenticated user role and assigned to the student role for an organization who is limiting site membership this configuration means that even if someone managed to create an account on the site they would have no rights until an admin assigned them into a role wiki users in this role can create wiki pages and can revert revisions it s also worth noting that this site uses a generic school paradigm it contains a student and instructor role and instructors create assignments within courses however if those roles aren t used the hierarchy is effectively flattened  permissions roles site configuration
