Thats tragic! :(
I never met with that guy but I spent some time making an QWK program for RISC-OS (Archimedes). RIP Mark!
OMG - I loved .QWK and the universe around it. Indeed I often lament the wish that web forums would support something like QWK so I could use a reader/editor of my choice - web forums suck.
What a senseless tragedy :(
