Jon, I agree. I am interested in the legal issues.
The personal rehashing would be better dealt with by PMs, imo.
FWIW, over the years I have found hundreds of musicians, right here at Mudcat, whom I would never have known about and have their CDs as a result, as well friendship with some. Didn't need any myspace to accomplish that!:-)
Richard, thank you for sharing your legal expertise. My brother has been looking into ways of putting his music up on the web. I'd seen a little bit about myspace, but will NOT recommend it, esp. based on what you have told us. Much appreciated.
