Gynaecon is a feminist mini-convention which is held at Swancon. It was inaugurated at Swancon 2000.
The program is not official, but is advertised ad hoc in places such as public toilets at the convention venue.
Discussions are usually round-table, and held in private hotel rooms. They are normally open to all, although occasionally they are closed to men.
Gynaecon has also provided panels within the main Swancon programme.
Gynaecon now has a Livejournal Community located here:
