use the login i have put a link to above, also you can add this to the footer with footer edit plugin, shows more stuff when people login to facebook 

or add to header with header plugin,or any where as long as it is the whole site the code is used on.

//
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=APPID;
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// ]]>
