"They said it was an open call."
Open calls are usually only for Equity actors. A non-equity person can't just "sign up". If anything, they would have to show up on the day of the audition and wait until every Equity actor has been seen.
If they are doing an open call for non-Equity actors, it's usually for a difficult to fill role like the little boy in Miss Saigon.
I know Glee isn't in the realm of reality, but we don't need thousands of "Gleek of the Week" kids descending on the city thinking they will immediately be cast in a Broadway show.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
