You probably want to contact the volunteers running the next BiCon rather than here.
If you do want to contact this site, email firstname.lastname@example.org
The address for BiCon is
c/o Equality Network, 30 Bernard St, Edinburgh EH6 6PR
This is using the lovely Equality Network as a mail forwarding service – mail goes to the organisers of the next BiCon, but it may take some time to get there.
