[xwiki-users] Registration page code

Hello! On the user management page ( http://platform.xwiki.org/xwiki/bin/view/AdminGuide/User+Management) there is this info: "You can also customize the way users are registered in your xwiki by creating a XWiki.Registration page which will override the default registration page." All I would like to do was to add a little warning, so I'd like to just copy the current page code and add it.... but if I ask to view the XWiki.Registration or XWiki.Register page codes, they are empty. Where can I find the code for the current Register process? Thank you, -- Tiago Rinck Caveden http://caveden.multiply.com
