Let's start a "Lawyer Neeeded!!" thread with a link to this one. We need to get people onto this ASAP, and it might call attention to the problem more quickly.
However, it is my unqualified opinion that we don't need to slit our wrists just yet all at once. It might make more sense to get as prepared as we need to be but take a "wait and see" stance on things, only complying with their "wishes" when absolutely necessary.
It also might make sense to find out how all those Beatles, Doo-wap, R&B, C&W and other lyrics websites (and there are many) handle this type of situation. Have they ever encountered a problem of this kind? How did they handle it? What was the outcome? And lastly, have they ever banded together for strentgh, with jointly appointed legal representation (which Mudcat could take advantage of)? Max, a simple form letter to their webmasters could get the ball rolling on getting the answers to these questions and more. United we stand!
