FYI, in my complete email it says:
"You may send us occasional, substantive application updates if appropriate. Please send any such updates to
[email protected], attaching your update as a Word or PDF file with the file name in the following format: lastname_firstname_AAMCID_ date. You will receive a confirmation email. Please do not include other queries or information in the email; questions should be directed to our main email address."
It looks like they do accept pre-II updates for whoever is interested.
