The postcard tournaments ran out of steam. I think it was a combination of the explosion of TourneyBot tournies last year and the novelty of sending cards wearing off on the people who had played in lots of them. By our nature as online players it sometimes takes a lot of motivation to go out and buy postcards and then get to a post office. People kept asking to send eCards, but that rather lost the point.
I've retired the postcard tournament webpages to the FIBS archive:
