Joshia,
our heartfelt support for you and your family at the sad news of your father's illness. i've been there often. In the end, God doesn't let any of us out alive. There's noway out except UP. as in toward love, and the light. I have encouraged your Dad to place a nominal yearly fee for the use of service. Several years if fact, but each time he demurred. I know without ever asking that 99% of the users would be HAPPY to pay the fair fee for you to learn and run the system,PLUS make the honest profit it deserves.
i'm sure from my own fatherhood experiences, that despite what he might say, he'd be overjoyed to find you safe and secure financially using his work as a start.
Please feel free to PM me or
sopan123@pm.meicantread@trashmail.netfor anything.
i have started and run tech companies. I always admired your dad's just do it attitude, when encountering something he wanted to counter, ...spam. His work should be an OS or net provider standard upgrade option. It's a very important piece of work.
thanks
