<blockquote class="foswikiHelp">%X% Under normal circumstances, there should be no need to rebuild your %USERSWEB%.WikiUsers topic.</blockquote>

Sometimes, the %USERSWEB%.WikiUsers topic maintained by %SYSTEMWEB%.TopicUserMappingContrib may not reflect the true list of users registered on your Foswiki installation. This most commonly happens when:
   * You deleted or renamed users and forgot to edit the %USERSWEB%.WikiUsers topic, or
   * You migrated a TWiki installation and accumulated new registrations on the new %USERSWEB%.WikiUsers topic before you had a chance to initialise it with the old list from the old !TWikiUsers topic.

Assuming your wiki is configured to use %SYSTEMWEB%.TopicUserMappingContrib, the script below should refresh your %USERSWEB%.WikiUsers topic with an accurate list of users. It uses the [[%SYSTEMWEB%.VarUSERINFO][USERINFO]] macro, which protects user information from ordinary users - so this topic needs to be viewed with [[%SYSTEMWEB%.AccessControl#The_Super_Admin_Group][admin privileges]] in order for it to be useful.
