If you want to see the Facebook like box, please click on the Facebook symbol.
The fan box is a Facebook plug-in. If you call up this plug-in, the browser establishes a connection with Facebook servers. Facebook directly transmits the content of the plug-in to your browser, which integrates it into the website. So Facebook receives the information that a special Internet site has been called up. If you're also a member of Facebook and are logged in, Facebook can assign the visit to a Facebook account. You can obtain information on the applicable Facebook data protection provisions at http://www.facebook.com/terms.php.
