I have had a few emails this morning from ould forumites trying to use their old log in name and password for the Letters Forum. These dont work, everyone has to join from new as the system is all new. But it's very easy.
The Comments section, where you can comment on features and politics and so on is open to absolutely everyone. No membership required on that.
So in effect we have two systems running and two different ways of communicating so there should be something for everybody and access for everybody one way or the other.
