Many news systems don't understand expiration dates, and some don't grok cancel messages. CD-ROMs can easily carry cancel messages, too, by the way -- they are a transport medium. Next bright idea? Anyway, people who want to use the law to restrict distribution of their news articles are extremely foolish. Your words are out there and they WILL be read. Forever. You can't help it. If you find your words embarassing, don't say them. .pm Jim Nitchals says:
I've already said it. I own the copyright to my posts, and only permit them to be distributed by Usenet because I can *cancel* and provide expiration dates with my posts. CD-ROMs do not provide these standard Usenet message control features.
If I issue a cancel message, it's obvious that I'm asserting control over the further distribution of my content (sites that ignore them notwithstanding.) Any time a CD-ROM is published with my message, and it contains an expiration date or is later cancelled, the publication violates my right as a copyright holder to retract my message.

have any agreements between themselves and the posters regarding copyrights. Netcom and all the other internet providers receive postings "free" and a cd-rom manufacturer has the same "right" to use postings as any other internet provider.
My expiration dates or cancel messages are perfectly reasonable ways to communicate the way in which I'm exercising my copyright. Netcom and other service providers currently honor those communications, but CD-ROM publishers of Usenet news do not.
