Take a look at a class roster at the University of Vermont. You'll see the usual stuff there — last name, student ID and class year. But you'll also see something else. Next to some names, there are pronouns: "he" or "she," but also the gender non-specific "they" or "ze."
They may seem like a few more words on paper, but for some students, like Jeane Robles, having pronouns on the roster means a lot.
