No essays unless "you are a convicted felon - please explain in the space below" or a reapplicant, in which case:
"In the space provided below, please provide the Admissions Committee with a brief application history (including when you first applied and the number of application attempts). Please discuss any counseling that you may have sought from the Admissions Office; and most importantly, please describe in detail the ways in which this application is superior to previous applications."
All others, just send money.
