 $post_author_description=get_the_author_meta("description");
 $html="<div class='clearfix' id='about_author'>n";
 $html.="<img width='80' height='80' class='avatar' src='http://www.gravatar.com/avatar.php?gravatar_id=".md5(get_the_author_email()). "&default=".urlencode($GLOBALS['defaultgravatar'])."&size=80&r=PG' alt='PG'/>n";
 $html.="<div class='author_text'>n";
 $html.="<h4>Author: ".$post_author_name."</h4>n";
 $html.= $post_author_description."n";
 $html.="</div>n";
 $html.="<div class='clear'></div>n";
 $content .= $html;
 }
return $content;
}

 RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC]
 RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC]
