Given the objections I've received, I now amend my proposal from "sign your messages, or else" to "make something that looks like a signature, or else". This has several consequences that I particularly like.

Wouldn't it "look like a signature" if I just copied at the end of an article the actual signature of some other, signed, article? That would be a true signature, just not mine and not for this article. It sounds as though it would meet the suggested requirement, but I don't see how it would accomplish the goals. I could do it with a macro, or maybe use a special .sig for posts to this list. It wouldn't add anything to my software. What am I missing? -George
