<p>Roles allow you to fine tune the security and administration of Drupal. A role defines a group of users that have certain privileges as defined in <a href="@permissions">user permissions</a>. Examples of roles include: anonymous user, authenticated user, moderator, administrator and so on. In this area you will define the <em>role names</em> of the various roles. To delete a role choose "edit".</p><p>By default, Drupal comes with two user roles:</p>
      <ul>
      <li>Anonymous user: this role is used for users that don't have a user account or that are not authenticated.</li>
      <li>Authenticated user: this role is automatically granted to all logged in users.</li>
      </ul>
