Thanks for the answers. I understand the need for statistics.
However, the friends I do this for are "afraid" to touch the buttons and don't want to screw things up. Have you never aided 70 year olds? They upset easily. It's not a pretty thing.
I see it's true now I need only push a button to re-register them but they're 100's and thousand miles away. I have used TeamViewer in the past and don't mind doing it, but it's a hassle for me.
Besides, my re-register didn't work and I had to go through email.
I only bring this up because it strikes me as a little cumbersome. Most people don't want to know how to do it, they just want it to work.
