@scientifics It does... sort of. From what I've seen, there's a lot of doubt about the quality at different points of access (app vs web vs files, etc) and sharing is, uh, complex at best.

There's a chance I'll find something in Apple's documentation or third-party literature, both of which are preferable to any of the aforementioned websites. However, from what I've seen of Apple's documentation it is not neccesarily as thorough or flexible as it needs to be to answer quick questions; I'm guessing that is why they made the official support account on Twitter.
