Hi Kent, I appreciate your response but why was it sent to you and not to me. I sent Phil an e-mail and so far, haven't heard back from him. Plus at the end of this message there was this: >>You are not allowed to post to this mailing list, and your message has >>been automatically rejected. If you think that your messages are >>being rejected in error, contact the mailing list owner at >>pianotech-owner@ptg.org. Why am I not allowed to post anywhere on "this" list? Just curious what that is and why it's there.
