I thought my record was broken when I got the mail:
Thanks for expressing your interest in our [position]. We are very much looking forward to reading your work. We can only accept applications in hard copy, so I encourage you to send it to me later this week; in the meantime, I will hold your electronic copy.
So I wrote that on my to do list, and had been home from Thanksgiving for several hours when I got an email that the administrator's computer had crashed. She needs all the applications again, and I can send by email or FedEx the hard copy. As if those are budgetarily the same thing. I resent my email.
The response then came: "Perfect! We're all set, [New Postdoc]. Many thanks."
So it looks like I don't need to send a hard copy, after all.
My record remains perfect. I am guessing that since I sent it on the deadline, the committee wanted to meet right away and needed the applications right then.
