Howard, thanks for putting up the poll.
Sorry I made it so difficult for some of you!
I'm home again, with a reliable internet connection. While away, I managed to log on to CC once, even type a message, but when I wanted to send it, I was told the site was 'out of bounds, ' or 'prohibited,' or something similar. I could use the back button, but when I tried to sign out, I got the same message.
So, I only used it to check my email, which was a slow and laborious exercise.
