To make USERNAME work, add these lines to MediaWiki:Common.js:

// Replaces with the name of the user browsing the page function UserNameReplace { if(typeof(disableUsernameReplace) != 'undefined' && disableUsernameReplace || wgUserName === null) return; $("span.insertusername").html(wgUserName); } addOnloadHook(UserNameReplace); // End of the replacement

However, it appears that custom JavaScript is disabled on this wiki. I don't know how to enable it; maybe contact the staff about it?
