actually, looks like this is the only way your email would work for getting a pin sent to you:
If you are a returning student who entered HMS prior to September 2004, your E-mail Addres is your official Harvard email account. You can receive your PIN by e-mail! Enter your E-mail Address in the "Student ID" field and click on the "Receive PIN by E-mail" link at the bottom of the "Log In" section. Your PIN will be sent to your HMS e-mail address right away.
It doesn't say that email comment for incoming students or returning students after 2004. also, i feel like it probably won't become active until monday, the 17th since it does specify a date. finally, it specifically says: If you have not yet been admitted to Harvard Medical School, you cannot access this system.
I feel like they are talking right to me. Ok, enough, i'm not checking again until someone says they're in. Boredom and curiousity got the best of me.
