hehe one thing's is for sure you won't find a person like that on an on-line forum
I have a friend that don't use computers, but he also despises any technology in mobilephones that goes beyond talking and sending SMS, I would guess that is quite common amongst computer unintrested pepole.
I think you will have to look amongst pepole that is so poor they can't afford a computer to find such a person. Maybe do some targeted advertisment in a ghetto or something?
good luck anyway, I can definitly see the value of studying such persons.
