This works only for logged-in users who use the $babelsyntax notation on their user page. Furthermore, the $bmc variable must be set up for your wiki in the InitialiseSettings.php file. See the documentation of the Babel extension. If you have a Babel box on your global user page, then the languages that you defined there will be shown on wikis on which you don't have a user page.
