Thank you for your help with this. It was a daily email of new posts I received from the forum, and no longer receive. Nothing to do with my subscriptions....links to all new posts were included in the email. At least, that is my understanding.
I used the 'Contact Us' link again, still no reply.
My emails have stopped also. When we changed to the new format I started missing the odd email then quite a lot then they stopped altogether. That was a month ago. I have tried most of the buttons I can find but have not found one to restart the emails yet. Then they say the first place you go blind is in the eyes!!!
