Are there currently *any* web forum(s) that enable forum/mailman mirroring ? In other words a Mailman email going to a web forum and vica versa ?
Precisely what does a "web forum" do? Would Trac or Roundup serve?
These are nominally "issue trackers" (and Trac is bundled with a wiki which might or might not be attractive for your purpose). However, what they basically do is manage threads. Roundup is quite good at integrating mail and web submissions at least for its purpose (but it doesn't thread automatically; instead, each issue might be thought of as a manually specified thread). I don't know how well Trac handles mail submissions, I only use the web interface of the Tracs I deal with.
Roundup is a hairball, but very very configurable. Trac is a lot more slick but at least in the incarnation where I met it (bugs.macosforge.org circa summer 2007) it was a ponderous unconfigurable beast requiring massive admin attention to get the smallest tweak implemented (or maybe it's just that the MacPorts folks can't admin their way out of a paper bag, I've seen other symptoms to suggest that's the case, so don't take this as entirely negative on Trac -- not to mention that lots of people love it).
I've briefly mentioned integrating some Roundup functions with the mailman interface to Barry but that hasn't gone anywhere yet.
