Couldn't you use the misc.php?do=$userid as the link posted and then in a pluging get the userid (remember i know nothing of JS )

PHP Code:

<script type="text/javascript">
    function vistedurl()
    {
     $UnSubsUrl = window.location.href;  
    }
</script> 


like this

PHP Code:

if ($_REQUEST['do'] == 'vistedurl')
{
$uid = substr(  $UnSubsUrl , strrpos(  $UnSubsUrl , '=' )+1 );
} 


that line will find the last occurrence of = and give everything after it. Ok thats probably messed up but it might give you an idea for the link they can click to unsubscribe in a 1 click action if the plugin then has a query to unsubscribe the userid

If you do happen to sort this code out as a one link click (vb3 & vb4 hopefully) i'd like to see it
