unified auditions- what is it?

Unified auditions are for people to audition for a bunch of different colleges without having to travel to each one individually. Representatives from a lot of college theater programs come to the big cities (New York, Chicago, San Fransisco) so you can audition for all of them at one place. It's way cheaper that way. You "sign up" for them just by applying to a college and telling them you want to set up an audition time-slot at the unifieds in whatever city you choose, then they'll give you a time and date.
