Maintaining family computers. (Score 1)

The relatives need to understand that you are providing them a free service that should not be taken advantage of. I got into the tech business because I got tired or paying $75 to $125 every six months to have our family computer repaired. If you were to suddenly be unavailable when these mysterious "just quit workings" happen and the family had to result to the alternative, I beleive they would either learn safe computing or give up computing (which isn't likely).
