I have assumed that material posted on an e-mail list remains the intellectual property of the author and should not be forwarded to other lists (or posted on web-sites) without the permission of the author. I distinguish lists (even non-confidential) or maybe I should say with subscription that's open or open, confirm, from public usenet posts. Does it matter if notebooks are set private? Am I correct or does my assumption only apply to confidential lists? What if I were to post material on my web-site that originated on our list and I could not locate the author? Thanks!
