title: How to display the "custom nickname" on Wordpress Comments?
body: <p>When I post a comment, it prints always the non-editable nickname set on the Users CMS area.
  I'd like to print the custom nickname (the one that can be chosed by dropdown list).</p>
  
  <p>I actually use <code>comment_author_link();</code> and seems it is not enough. How can I should use?</p>
