So I go to http://developers.facebook.com/apps to try to begin to add an app to a page. The page has 26 fans and I was allowed to create a vanity URL but the page does not appear on the apps page. Anyone have a reason as to why this is the case?
It is not going to be there. http://developers.facebook.com/apps lists apps that you develop.
Go to the app page, then click "Add to My Page", from there you can add an app to your page.
