How to find how much space left in my Document Cloud storage?

Yes, this would seem like a basic functionality that should always be included, unless the design is intended to make sure someone using the free service finds out at the worst possible time that, surprise! they just ran out of room, and cannot complete their project  and meet their deadline without wasting time deciding what to delete, or subscribing to the paid version. Someone learned, while getting their MBA, that panicked consumers tend to spend more money. This is capitalism at its worst. I'll be really surprised if this comment isn't removed or my free account revoked because speaking my mind here violates some crappy terms of service.
