Forum OpenACS Q&A: Re: Excellent New Site
That said, the hash solution you propose is one we considered. It could be done, even if it's going to make the From addresses even uglier.
I wonder what happens to the Reply-To: header when an email is forwarded - maybe it even gets discarded by most mail programs which would be nice in this case. I just tested it with mutt: it discards the Reply-To: header.
Another issue, propably solvable with a smart regex, would be the ignorant full-quote-at-the-bottom that many people just seem unable to avoid, and which would just look terrible in a forum.
I agree with Ben that openacs.org is the wrong place to try this out, though. Maybe it should never be enabled for the public site, but this functionality certainly makes sense in other settings, e.g. an intranet that consists of trusted users only.
