From Colin MacDonald:
In case it helps, I’ll certainly not complain about anything I still hold copyright to going up - although all the Fred magazines are already up, there were some other mags I got in the end (Enceladus, SCPDU, Outlet), and of course, all the commercial software - although I should point out that certainly the copyright to the code of those will have reverted to programmers long ago, but design, art, audio and other rights to most of the titles probably still rest with me.
