From: "JEFF LICQUIA (CEI)" <JLICQUIA@mhc.uiuc.edu> Really, the only "unknown" with signed messages is whether they are valid or not; it's pretty easy to distinguish the unsigned posts. The purpose of adding a header line to mark unsigned articles is _not_ to indicate that they aren't signed, it's to editorialize on the fact that they're not signed. There has been an argument that since marking doesn't accomplish anything you couldn't already see, that it's useless. Fine, the premise is specious, because it's not intended to mark unsigned posts, it's to comment on them. May I propose a "better" way (you be the judge here): Proxy the job. A proxy should have it's own subscription list, which makes it an opt-in system. Other than that, I think a verifying proxy is a good idea. Eric
