Where did you find that? The tooltip I saw says they store files up to 5 GB on their servers, but it doesn’t appear to give you a choice. It also says that for files larger than 5 GB, it will use p2p (that answers one of my previous questions, I guess), but it still says “up to 10 GB.”

Why would there be a 10 GB limitation for p2p transfers if data is not being stored remotely?
