You must be referring to the template that displays the username of the logged-in user viewing the template. That can be found here. However, in order for it to correctly function it requires the following code under MediaWiki:Common.js. (admin rights required to edit MediaWiki)

$(document).ready( function {   if(typeof(disableUsernameReplace) != 'undefined' && disableUsernameReplace || wgUserName == null) return;   $('span.insertusername').each(function { $(this).text(wgUserName); }); });
