I just installed. I noticed this script in my page:
Code:
<script type="text/javascript">
<!--
vB_AJAX_ThreadRate_Init('showthread_threadrate_form');
var threadid = 17;
//-->
</script>
It was properly untouched. I haven't tested it extensively, but it seems to do the trick. I don't know the real SEO affect of something like this, but I do like the idea of removing a lot of template-related comments from the code.
