I just thought of something I need to add.
There was a time in my last marriage during which I had an online relationship of a sexual nature with another man. This was approx. 11 years ago...so hard to believe. At that time I did have a private email box and took measures to keep it secret and was successful at it for almost two years. During that time (and particularly after being 'caught') the nature of the relationship became that of an intimate friendship. And inconceivably enough, we are still friends to this day. That's beside the point though, I guess. I don't think I've ever talked about that here before...
But I mention it to hopefully free up the atmosphere and dispel any illusions that this thread is meant to judge or condemn people for their actions to protect computer privacy. I'm well aware that we are all human. So there.
