Have you ever thought about going into an assisted living facility and showing the senior citizens how to join forums? I’m not sure how many actually have laptops/computers, but those times will be changing to where more and more have them, I believe. I do know one friend from church took his laptop when he moved into one last year.
Sometimes seniors could be really lonely, and forums could fill that gap. Maybe this is a project for high schoolers who need community service hours?
