I would hang in there if I were you. My mom is 77 and she enjoys keeping in touch with all of us. There are three generations all connected. She plays games, enters contests and messages her kids and grand kids. She still hasn't figured it all out yet, but enough to go on and check every night for a couple of minutes to catch up on the days events.....there are lots of privacy concerns about facebook, but, I honestly have never had a problem, nor do I know anybody who has ever had a problem because of their association with facebook. I think it is in their best intrest to keep things secure, because if there were any kind of scandal, they would lose millions of members emmediately...
But, of course, that is all up to you.
