QWP: Readercon's administrative structure:
The board of directors is elected from the concom; they serve different functions. The board's job is to handle business matters such as the disbursement of funds. (For example, the year that half our proceeds went to the Paul Williams Fund, that was a board decision.) The concom's job is to make the convention happen.
There are annual board elections. I believe we'll need a special election to replace the board members who resigned, and they'll only serve pro tem, until the next annual meeting in January. The concom is a much more static body; once you join it with the rest of the committee's approval, you're part of it until you decide to leave (or, in an extremely rare circumstance, voted off by the rest of the committee). For each convention the conchair and program chair are selected by the concom, and then concom members volunteer for the various duties necessary to make the con happen.
