My grown kids seemed to enjoy Facebook so I went on to it, I don't 'do' much chatting on it as there's only a tiny screen for that, and you know how I like to chat but the games are great fun. Also Jeff goes on there 'in my name' and plays the games as a bit of relaxation. My brother and sister in law have kept in touch with their son Paul in NZ through facebook. I think all my family are on it. One doesn't need to show 'On Line' which is good as well.
My Space. I've had that space for several years, more as a diary than anything else, about holidays and photos. Haven't used it for ages.
I've also joined another site in another country to communicate with a friend.
