Of my remote prep clients, most will upload to my Dropbox ('love' 😠 the ones who have the files as image_001.jpg, image_002.jpg via camera phone and I always select the wrong counter- or counter-clockwise rotation.)  Then the ones who mail their manila envelopes that the CIA and NSA would be proud of, clasp secured and taped ALL around, takes an effort to saw through it.

Documents that would surely clog anyone's toilet.
