You may not want the 'Click To Chat' graphic to appear on all pages - but you still want to track visitor activity on these pages.
You can do this by making a small change to the code:
<!-- Embedded ParaChat: Insert the script below at the point on your page where you want the Click To Chat link to appear -->
<script type='text/javascript' src='http://testdrive.parachat.biz/include.js?domain=testdrive.parachat.biz'></script>
<script type='text/javascript' >
sWOResponse='';
if(typeof sWOTrackPage=='function')sWOTrackPage();
</script>
<!-- End of embedded ParaChat -->
The Line
sWOResponse= '';
Tells ParaChat LiveHelp Server not to serve a visible graphic - so nothing will be visible on your page, but tracking and invites will work as normal.
