Bill,

To get the js-kit ratings widget to work on wordpress for multiple blog posts (it's really easy), I set it up this way:

In the single.php file, enter this code somewhere before or after the <?php the_content('<p class="serif">Read the rest of this entry &raquo;</p>'); ?> line:

<div class="js-kit-rating" path="<?php echo get_permalink() ?>"></div>
<script src="http://js-kit.com/ratings.js"></script>

This will allow each post's page to feature the js kit rating on it.

I also wanted to have the stars show up on each post when a person is browsing the main page and looking at many posts.  

To do this, change the main index template as follows:

Right after <div class="entry"><?php the_content('Read the rest of this entry &raquo;'); ?></div>
put only the first part of the js kit code:
<div class="js-kit-rating" path="<?php echo get_permalink() ?>"></div>

this will place the rating into each post.  Then, right after <?php endwhile; ?> add the rest of the code:
<script src="http://js-kit.com/ratings.js"></script>

The reason is that the last part of the code should only appear once, which is why you have it outside of the loop.
