Plans on PA for becoming an all-music site?

No only those that are 'progressive'. I've never taken any notice about the rules because you simply can't type anything and then wonder if they are a progressive band or not. What I think is progressive is more important than what is offically 'progressive'. However as an example you can have something like 'progressive electronic dance' ie Tame Impala. I would never start a thread in the progressive forum but would reference him in a discussion if there was a linked subject. Music is only real because it comes from the artist. Of course we are not children and don't either need ultra strict rules or boundaries. Well hopefully!
