Just want to register that I'm leaving this discussion, as whatever your intentions, I'm now feeling judged and found wanting for a personal decision which I took when someone very peripherally connected to me took my whole tree, and posted it to his own, without permission, without warning me, and including large numbers of people who were not related to him. I now share with connections to aid their researches and I am very free with the information I do share.
I defend the decision to make my tree Private, but I don't wish to discuss it any more. I share and contribute as much as I can, and several comments here belittle these contributions.
Rarely am I upset by discussions on this board, I like to feel I am a rational and sensible human and capable of understanding other people's opinions, but I am uncomfortable with this one.
