Dr. Tom Collins:

It is an interesting one. I am trying to recall it. When the forum was being established I was very keen for it to have as broad a representation as we could manage. To be honest, I had forgotten that non-registered users were excluded, but I never encountered any opposition to including unregistered users in the group. I was very clear that they had to be included as otherwise it would simply be people from one side talking to themselves. Keith Hyland might wish to comment.
