Have not been in touch with him for some time, but the last time we talked he emailed me from:
dan at stormsedge.com
URL is:
http://www.cnetbbs.net/Minus the spaces and replace "at" with @, of course. I don't want the poor fellow to get spammed to death from mailbots, heh.
Last time I spoke to him, I simply told him I was a paid customer for 3.x and I was looking for the latest version, and he was kind enough to send me 5.10h with a how to on setup and how to get a new keyfile off him, since I have no way to access my old original CNet disks.
He was a terrific help to me, anyways. Good luck!
Excelsior is free now as well, and is terrific and very CNet like if you ever wanted to give that a poke. I ran it for some time and it was absolutely bulletproof. DLG is also now free (including source!) and on Aminet.
Good luck on reaching him.
