I have started a draft Reference Manual for DKos5/DK5 on Booktype, where you can join in the process. We need writers, testers, editors, and at least one graphic artist, to do a better cover. This assumes that you have used or are willing to try the DK5 Beta, of course, so that you can examine where everything is, and test how it works.
You are not required to like DK5. In fact, part of the project is to break DK5 as much as possible and complain about whatever doesn't work to further our community goal of More and Better Kossacks working toward More and Better Democrats.
