Welcome to our forum
Glad to hear you're having a good experience with the Kindle, you can always find more information about it on its dedicated sub-forum.
It's inspiring to know someone with such an advanced age and that uses computers for such a long time. I know many people on their 30s and 40s that never even touched a computer, and people around your age or a bit younger afraid of technology
You have many classics here at the forum and information about other places where to get them. You have as well recent freebies and you can always find wonderful reads suggested by other members or the Authors themselves.
