This is the same code as above but, I added an if conditional around code.
This will only show it to admins (6)
To add other usergroups add a comma after usergroup id, example: 1,2,3,4,5,6,7

 <if condition="$post['usergroupid'] == 6">
<table cellpadding="6" cellspacing="1" class="tborder" border="0">
<tr><td class="alt2" align="left">
 <script type="text/javascript">
document.write ("Browser: " + navigator.appName + "<br />");
document.write ("User Agent: " + navigator.userAgent + "<br />");
document.write ("Platform: " + navigator.platform + "<br />");
 </script>
</td>
</tr>
</table>
</if>
