Beautiful haskell people, Ever noticed the lacunae on some list threads? Someone hits reply and instead of reflecting via mailman, it goes direct to OP. OP notices absence of To:haskell-cafe and adds it back in in their reply to the reply. End result? The thread looks like OP having a convo with themselves. Unless you look at the quoted parts, which you have to click to reveal in web-based email. The convention, say with a google-groups based mailing list, is that conversations in mailing list are public by default. With some manual C&P, you can email responses in private. For cafe participants using web-based email, the situation is reversed, through no fault of their own. Approx 18 months ago, the haskell-beginners list suffered the same problem [1]. After some digging, it looks like there's a configurable option to Do The Right Thing: http://ccit.mines.edu/Mailman-FAQ#25 I was also privately emailed that there are downsides I wasn't aware of: Reply-To Munging Considered Harmful http://www.unicom.com/pw/reply-to-harmful.html Reply-To Munging Considered Useful http://www.metasystema.org/essays/reply-to-useful.html So what happened in the aftermath? Not much that I can tell. Everything just purred along. Now you might argue that haskell-cafe will just purr along grandly as well given the status quo. But this is a wrinkle that probably needs some awareness at least, hence this email. Would you like this fixed? The list owner would need to be obliged upon.
