 	Role
+		A role gives users permission to perform a group of tasks. When a user logs in and is authenticated,
+		the user's role determines which capabilities the user has, and each capability is permission to perform one or
+		more types of task. All users with the same role normally have the same capabilities.
+		For example, users who have the Author role usually have permission to edit their own posts,
+		but not permission to edit other users' posts. WordPress comes with six roles and over fifty capabilities in its
+		role-based access system. Plugins can modify the system.
