 * It is not recommended to restrict view access to individual topics since all content is searchable **_within_** a web.
 * The view restriction is not suitable for very sensitive content since there is a way to circumvent the read access restriction.

+**_NOTE:_**
+
+The above schema can lock completely a topic in case of a typing error of the ALLOWTOPICCHANGE setting (see [UnchangeableTopicBug](http://www.twiki.org/cgi-bin/view/Codev/UnchangeableTopicBug)). To avoid this:
+
+* set the `$superAdminGroup` variable in `TWiki.cfg` to the name of a group of users that are always allowed to edit/view topics. E.g.:
+
+    $superAdminGroup = "TWikiAdminGroup";
+
+* the default setting is not to have superusers
