I'm not sure I can contribute the time required for this cause.  I can devote two to three hours a day (by rising at 4am) because I want to learn more about Windows 95, Netscape Navigator, and reduce the number of General Protection Faults I see on my screen.
I am a 70 year old retired electronic engineer, doing part-time telecommunications consulting.  Married, active ham (W4ZBT) for 46 years, have three IBM computers: XT-286, PS/Value Point 386, and this PC360 200MHz Pentium w/64 MB RAM, 2 GB & other hard drives, scanner, CD reader & HP CD Writer Plus, IBM laser and HP color printer.
Not enough hours in the day!  But experience is the best teacher.
