Actually it was my partner that contacted you. There's a lot of confusion regarding the name. The author of the coin up version, Jeff Kulczycki, was thinking something like "Y2K" when he decided on "D2K". Most people think it's a typo, and call it "DK2", "DK II", etc.
We don't really mind what people decide to call it… But for the purposes of search engines, can you add those as tags?
We would really appreciate it, and thanks for the terrific review!
