Gynaecon is a feminist mini-convention which is held at Swancon. It was inaugurated at Swancon 2001 by Emma Hawkes, Sarah Xu, Sandra Norman, Gina Goddard and Elaine Kemp (needs checking).
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 now has a Livejournal Community located here: 
Some examples of topics which have been discussed in the past:
- Non-gendered pronouns (ze, zer)
- Building communities
- Is there sexism in Swancon programs?
- Alternative methods of menstruation management
- Bra burning :)
