Graham this is what I use the bar will be where you put it
There are limits to what you can do as it is in a iframe
Put this where the auth bar is to show

<div id="auth"><xt:auth /></div>

Add this script anywhere below it

<script> var auth=document.getElementById("auth"); auth.getElementsByTagName("style")[0].innerHTML="#xt_auth_iframe {background: transparent;margin-top:2px}"; var iframe=auth.getElementsByTagName("iframe"); iframe[0].style.maxWidth="199px"; iframe[0].style.overflow="hidden"; iframe[0].style.height="23px"; </script>
