Glueman: your original question was "is folk self-regulating or decided from above"? My answer is "no, it is not decided from above. You can do what you like".
You also make a very strange assertion in your last post,that you disapprove of people having opinions of what is or isn't folk. Who is it precisely that you wouldn't permit to have opinions? Just people who disagree with you, or does it apply to everybody including yourself? I personally feel free to play whatever I like, and to define folk however I like.I would just like to check whether you would allow me to do this.
Just answer my very simple questions in my last post. It would clarify your postion for us: it is difficult to know what to argue with, as you change so rapidly.
