New to version 4.5 of Savvy Content Manager is the anonymous user and group.
The user and group is automatically created for you and by default given rights to view all objects. There are no other abilities that will function for this user or group but display rights. This is useful when you want to password protect content, pages or templates within your site.
The anonymous user is someone who has not logged into your site. At any given time many people may be viewing your site and using the anonymous user account automatically. In order for that visitor to use a different user account they must first log in as either a content contributor, or a member.
