I'm trying to highlight just the admin comments on a wordpress site. I've tried a bunch of tutorials and I've had no luck. If someone could help/point me in the right direction it would be greatly appreciated.

In the comments.php file I'm call ing wp_list_comments

        
    <?php wp_list_comments('type=comment&callback=cnc_comment'); ?>
  

This is my function in the functions file:

// Comments Callbacks, Pingbacks and Style
  function cnc_comment($comment, $args, $depth) {
     $GLOBALS['comment'] = $comment;  
     ?>
      id="li-comment-<?php comment_ID() ?> ">
     " >
      
          
       <?php echo get_avatar($comment,$size='48'); ?>
       <?php printf(__('<cite class="fn">%s says:'), get_comment_author_link()) ?>
      
      <?php if ($comment->comment_approved == '0') : ?>
       <?php _e('Your comment is awaiting moderation.') ?>
       

      <?php endif; ?>
  
      <?php printf(__('%1$s at %2$s'), get_comment_date(),  get_comment_time()) ?> 
<?php edit_comment_link(__('[Edit Comment]'),'  ','') ?>
            
      <?php comment_text() ?>
        
      
       <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?>
      
     
  

Thanks in advance, Mike
