A lot of things seem currently to be happening at the Gothic Chess homesite. I found a lot of more actual content. Even the link to the (expensive) wooden Staunton Gothic Chess set is working now (the first time for me). Therefore I hope, that all the other links and picture references will soon be working properly, too.
Maybe it would be a good idea, to also place written Gothic Chess license conditions (not merely its costs) at an appropriate position. I do not know, whether other chess programmers might be interested in that theme, but at least I am myself. Because I am not a lawyer and I never have used a license to a patented subject before, I have no idea, which implications it would have, to publish or distribute a patented Gothic Chess aware program under a license then.
