+<div>
+  In this mode, every logged-in user gets full control of Hudson. The only user
+  who won't have full control is anonymous user, who only gets read access.
+
+  <p>
+  This mode is useful to force users to log in before taking actions, so that
+  you can keep record of who has done what. This setting can be also used in
+  public-facing Hudson, where you only allow trusted users to have user accounts.
