Check out this 2009 thread by tvandyke on old CDO for more details: tvandyke received an E-mail from Tuomas Pirinen in 1999 and later shared his copy in old CDO’s exclusive Library (a section for veteran forum members away from prying eyes of lawyers, for instance). Ten years later in 2019, @PyroStick reformatted Tuomas’ playtest into a more readable format, and we used it as bait to get people to sign up to old CDO.
Now that we have Discourse and no dearth of new members, it should be safe and fine to put it up in our public Library section. It’s been 22 years after all.
Cheers!
