I have some before/after school kids here this year. One of them asked to use my computer today and I wasn't sure what to say! Mostly I'm concerned about the computer being damaged by the kids! I let my own school-age child use my computer, but he is supervised and knows how to use it properly. I think I'd just prefer that don't use it, but I wasn't sure what to say to the boy today. Would you let older kids use it or not (age 5-9)?
