We are about half a million active windsurfers worldwide.
Say half of us can read. That leaves about a quarter of a million.
Say half of these can read and write English. That leaves a bit more then hundred thousand.
Say half of those have access to the internet, and of those tenth attend internet-forums about windsurfing. Not many left, but still a lot more then the five that actually replied my request.
Will it help if I get on my knees and beg?
