I hate to disagree with my well-wishers, but I have quite a load at the moment and haven't been as fast these days. Please continue to send in essays, by all means, but you'll have to wait one to two weeks for a returned draft at the very least.
Send essays to:
jrapp@sas.upenn.edu
Include the prompt(s) and your intended schools
If you have a really urgent request (e.g., early action applicants) and have an imminent deadline, put URGENT in the subject line and I'll put you at the top of the pile. (Use the honor system, please! Only if you're really desperate.)
