David, and others...
It's impossible to give access to the old Yahoo forum, but I've made a small start in copying the messages across to our new site - You'll see the new message area at the bottom of the forum page.
You CANNOT post any new messages, OR reply to messages in that area. It's there purely as a source of reference.
Because I have to copy each and every message manually from the old Yahoo group, this is going to take me a long time, but hopefully I will get to the end eventually!
I won't be copying every message, as a lot of them were questions about accessing the Yahoo group, or automated file announcements etc etc, none of which have any relevance to this site....
