How many Eph frosh have been a "Unit Production Manager?"

From the Homer Tribune:

Noomah, who spoke from her dorm at Williams College in Massachusetts, said a lot more goes into producing film than what people might think – including some rather detailed logistics during each stage of the process. She and Edminster began making movies after she had roped him into a project while they were in the eighth grade.
“Then he called me out of the blue two years ago and asked if I would like to help him make this movie,” she said. “I made sure the actors had what they needed and made sure they had all the props. I carried a lot of things around in my car, which was pretty much a costume box.”
