<script type="text/javascript" src="http://static.ak.connect.facebook.com/connect.php/en_US"></script><div id="fb-root"></div> <script> window.fbAsyncInit = function() {   FB.init({     appId: "myapiid",     xfbml: true   }); }; (function() {   var e = document.createElement('script'); e.async = true;   e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';   document.getElementById('fb-root').appendChild(e); }()); </script> <fb:fan profile_id="253787057811" stream="0" connections="0" logobar="1" width="300"></fb:fan> <div style="font-size:8px; padding-left:10px">   <a href="http://www.facebook.com/pages/FanPageName/myapiid">FanPageName</a> on Facebook </div>
