Hello. I also had this question, so you sort of answered it for me, and I'll do the same for you. I also applied to Sloan Kettering, and due to an unknown error, they were missing one of my documents. I received an email stating that the application would remain open until December 10. I had already submitted the application, including the fee. Either the two of us are the best of the best :-) or it is generic. I was leaning towards generic when I first received the email.
