I added the “Edit Page URL” tab to my application, and then added the application to my fan page.
How can I access the edit URL directly from my faker page?
It is not as simple as it should be. As perx wrote on http://forum.developers.facebook.net/viewtopic.php?id=88920 ...
Click the "Edit Page" button on your fan site page. Then go to "Applications" and click "Go to window" next to the name of your application. This link will allow you to pre-set "Change URL".
You can also use signed_requestto find out if the viewing user is the page administrator and adjusts the content based on this. Here are the details of this here .
