Facebook has had an App Review process for a few years. While it's been a little tedious to explain why you want specific permissions, it has also generally been smooth sailing. Submit a request, get approval within a few days (or even hours). Done.
That all changed with the Facebook privacy issues earlier this year. Now, they dig deeper and, because of a large queue of submissions, take much, much longer. JFBConnect has been updated to help with the approval process and to improve your chances of getting approved the first time.
