Adding to your template
Use <?php cl_display_badge(); ?> in your comments.php file where you want the badge and checkbox to be shown

This plugin inserts fields to the comment form at run time. If you find there is no badge shown on the comment form after you first install it, please check your comments.php file for the command <?php do_action('comment_form', $post->ID); ?> before the </form> tag

For logged on users and administrators, be sure to check your profile on your own dashboard and make sure there is a url entered.
