Volunteers are solicited year-round. Those who register are added to a mailing list. Those on the list receive a mailing each fall which includes a postcard that can be returned indicating their interest in serving on a committee for the coming year or term. Positions are open on all three committees each year, but the number of seats varies depending on the committee. The names of those who have shown an interest in filling a vacant seat for the following year are placed into a random drawing and selected by the current year's committee chair. If there are unfilled seats, the communications department makes contact with those on the volunteer list until all seats are filled.
