Do I have to do anything about FB App review?

I'm sorry for the delayed response. We're actually working on multiple tools and documentation to help with the App Review process:
* The next release of JFBConnect (v8.0.1) will have a new App Review section in the administrator area. This will show all of the scope that your app is currently requesting from each network and where that scope is being required from (profile import, channel, posting permission, etc).
* Details on what permissions need to be submitted to Facebook
* Documentation on how to go through the App Review process

If you need to go through the app review process immediately, then you'll need to follow the directions in the Facebook Developer area. It's actually pretty straightforward, though I understand it looks tedious. Here's the general flow though:
* Go to the Facebook Developer area
* Click into your app
* Go to the App Review section
* In the "Current Submission" section, add the permissions you need approval for. We recommend doing a group at a time, like just the permissions you require for fields you are importing from a user's profile or just permissions for allowing JFBConnect to read and post to a Facebook Page on your behalf
* Attach screenshots or a video (can be taken with a cell phone aimed at your monitor, nothing professional required) of the authentication process and how the permissions are used (to populate the Joomla user profile, for example)
* Submit

To currently get a list of the permissions you're currently requesting, you can open the HTML of your home page. Then, search for "jfbc.login.scope". You should see a string like:Those fields in the list are the permissions you should submit for review. Again, the next release of JFBConnect will make this more clear in the administrator area.

I hope that helps you get started, but if you need anything else, just let us know. We're shooting to have the updated release out by the end of the month.

Thanks,
Alex

It depends on the permission. Photos and video aren't required for all, but the more details you can provide and the easier it is for the reviewer to understand, the better your chance of getting approved the first time.

When you "Add items" (the permission you want to have reviewed) to the App Review request, it will give you a set of instructions on what to do. I'd recommend looking into starting an App Review process. There are a lot of details, but Facebook has a bunch of instructions on how to do it, which is the best place to start. They also (like everything else) change their instructions and requirements as time goes on to make sure that the submissions have all the required details to make it smoother... so look there first even without any documentation on our end.

As for batching of app reviews, you can do them all at once.. each permission requires a description and/or video/screenshots or whatever. You can do it all at once, but my feeling is to do it in groups of related items.

Thanks,
