Conventions of the SF community are volunteer-run and community-based and have members -- they do not sell tickets. The ideal (which is not always met, of course) is that everyone -- convention committee, ordinary fans, program participants, artists, hucksters -- is working together as a cooperative group to create the convention.
This manifests in a number of ways:
- A single membership provides access to everything (except a banquet if there is one). There are no separate fees for autographs or special access.
- Members are expected to participate in discussions at panels. Part of every panel is devoted to audience participation.
- No one is paid for working on a convention. Everyone provides their time as a free gift to their fellow fans.
