The commentators are a fundamental part of any blog, since they are the ones that give life to the blog, opening and replying to discussions which leads to more activity in the posts.
It is therefore very important to know which are the most active users of your blog, the users who leave more comments, and for this reason, today I present a great method to display a list with the top commentators.
This Top Commentators gadget comes with user's avatar and is done with JavaScript.
1. To add this gadget, you have to go to

2. Select the
<style type="text/css">
.top-commentators {
margin: 3px 0;
border-bottom: 1px dotted #ccc;
}
.avatar-top-commentators {

border-radius: 30px;
}
.top-commentators .commenter-link-name {
padding-left:0;
