When I clicked "Start a new discussion" without being logged in I got this message: "The action you have requested is limited to users in the group user." Not very helpful is it? Can it be changed to the "You need to be logged in to start a new discussion ... etc."
Oh, BTW I originally wanted to Start a new thread to say thanks and well done to Erik for getting this system online. I always kind of enjoyed being a guinea pig for new technology :-)
