Each user is assigned a role. Roles grant permission to perform various actions, e.g. edit the content of a text widget. A given user may only have one role at any time.

The 5 roles are:

• Everyone
• Registered User
• Contributor
• Editor
• Administrator

Each of the roles grant permissions. These permissions are cumulative and listed in order of least permissive to most.

• Everyone - all unregistered, guest users have this role. May only view the site.
• Registered User - all registered users have this role (if they have not been granted another role). May only add to or edit content that they own.
• Contributor - Permission granted to add new content owned by others.
• Editor - May edit or delete content owned by others.
• Administrator - May perform any and all actions.

Each widget is assigned an owner when created. Initially, this is the user that created the widget. The exception to this is that a Guest user may never own a widget. The owner of a widget has permission to execute all configured actions regardless of the permission requirements of those actions. In other words, the owner of a widget can change a widget.
