Longtime user of sheets only, here. Thanks so much for this downoad/upload mechanism, it is a great help, and not only for the purpose of safekeeping. It's unfortunate that this came to be as a consequence of a great disaster. But I would like to commend everything you have done in the aftermath - owning up to the mistakes, offering an honest apology, and taking fast steps to protect against a repeat.
