I had a professor who was barely computer literate. He could type on a keyboard, but that was about it. I am, however, the Queen of Word Perfect. When his book was accepted for publication, I got a summer assitantship converting his files into camera-ready art. It was a relatively cushy job, albeit a bit hard on the hands. With the help of a few macros, we converted the text fairly quickly.
The problem was that for months afterwards, he kept calling me at home for help formatting his work. I don't have a computer at home, so I would have to mentally recall each pull-down menu and walk him through the process. The information transfer was often unsuccessfull, so I'd have to make a special trip in to his office. And at this point, I wasn't getting paid either.
Lately, I've been doing the same with knitting, and somehow I don't mind as much.
