Gareth I was going to send a link (to this thread) to a local folk club organiser. then I had a look and realised that for someone coming late to the discussion it is difficult to follow. This might be why I did not understand the point when looking at some of the very early threads on this topic. So would it be possible for someone to sum up the state of play in very simple terms. A webpage with a very simple explanation and links to more detailed info would be a great place to send people new to this topic.
