Haloscan Comments and Trackback
I've got Haloscan comments working now, thanks to this blog posting.
I have also been able to apply the same principle to get Trackback working, by adding the following lines after the code given for the comments (replace XXX with your Haloscan username):
<script src='http://www.haloscan.com/load/XXX' type='text/javascript'> </script>
<a expr:href='"javascript:HaloScanTB(" + "\"" + data:post.id + "\"" + ");"' target='_self'>
<script type='text/javascript'>postCountTB('<data:post.id/>');</script>
</a>
