Adding Post Only Comments On Tumblr Ii

It seems that Tumblr now has a custom block:Permalink block which is rendered only on permalink pages.

So, to add post-level comments, add this piece of code inside a block:Permalink block.

{block:PostTitle} 
  <div class="js-kit-comments"></div><br/>
  <script src="http://js-kit.com/comments.js"></script>
{/block:PostTitle}
