The NewDuplicateUserMessage extension adds a message to the talk pages of newly created duplicate user accounts, which are determined by email address.

This extension was forked from the NewUserMessage extension. See the documentation for the original extension NewUserMessage.


  • Download and place the file(s) in a directory called NewDuplicateUserMessage in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'NewDuplicateUserMessage' );
  • Configure as required.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


Create the "Template:DuplicateUserWelcome" page on the wiki:

== Duplicate user message ==
You have duplicate accounts: {{{duplicateUsers}}}.

The configuration is the same as the original extension NewUserMessage except instead of "NewUser", use "NewDuplicateUser".

For example:

  • Instead of $wgNewUserSuppressRC = false;, use $wgNewDuplicateUserSuppressRC = false;.
  • Instead of "MediaWiki:Newusermessage-template", use "MediaWiki:Newduplicateusermessage-template".
