From the email I received from YSOM adcom:
"Admissions Decisions: All SOM Consortium admissions decisions will be sent by close of business on February 25, 2011. You will be contacted by our office via email when your admissions decision is available. By the beginning of February 2011, we will send log-in instructions for our SOM application site which you will use to access your SOM admissions decision on February 25, 2011. Our application site is to only be used for viewing your admissions decision. "
Maybe there won't be calls from the adcom - just changes to our status on their site. That how my Duke decision was delivered.
