It depends on the template you are using. I am using Golden Eagle Lite. In this case, I located the comment-template.php file and commented out the ‘comment_notes_after’ paragraph in order to make the default text disappear.
//’comment_notes_after’ => ‘<p class=”form-allowed-tags”>’ . sprintf( __( ‘You may use these <abbr title=”HyperText Markup Language”>HTML</abbr> tags and attributes: %s’ ), ‘ ' . allowed_tags() . '
‘ ) . ‘</p>’
It worked!
