A paper-free office?
I applied and was accepted EA last year and simply had the school send my letter of good standing on. I guess the paper-free thing is part and parcel of their green initiative -- as a result, we can no longer purchase bottled water on campus. I suggest you get in touch with Krystal Orr in the WUSTL admissions office and ask her how to submit it. Good luck, and feel free to get in touch with me.
