Volunteers will be ushering for MACfest, a concert of all University of Michigan A Capella groups to perform with their new members. Volunteers will need to arrive at Rackham Auditorium at 6:15, which is 15 minutes before the doors open. Three volunteers will be assisting with ushering, and four will be helping with ticket sales. Please indicate in the comments if you have a preference of which task you would like to do.
