Main subfield is IR! Also, the email was very specific to me so I don't think every accepted person got a personal email yesterday. Just wanted to pass on that I was told official acceptances were coming this week. Good luck!
I was notified yesterday that I was accepted by a faculty member. I think he was acting on his own because he said official acceptances would be coming out in the next few days. So, no not all acceptances have been sent out.
