We now have agreement to hold a stall at the Mind Sports Festival in Cardiff on September 14-15th. This will be run by the British Go Association in conjunction with the Cardiff Go Club.
There is some information about this and other Mind Sports Festivals here: http://www.mindsportsfestivals.com.
The Festival will host competitions for (currently): Chess, Scrabble and Magic, with about 400 registered competitors so far.
We expect to have good opportunities to promote Go to like-minded people during the Festival, when they have intervals in their play or are knocked out.
