Yes, you can set a Google Group to behave like a normal mailing list; see the link to the Help article that says as much, which I posted in one of these threads. You can also reply in the same manner/paradigm. I've found Google Groups to be better than Mailman at maintaining threading (though both are vulnerable to Digest replies that splinter threads). I think an end user's email client has far more influence on maintaining threading than the relay software (listserv or web or pigeons or whatever).
Of course, if one makes a new subject line, one can break the threading (as on Mailman).
And I realize some confusion, here: I and other haves conflated groupware with web forums. Regarding a Group, yes, every single one that I have seen behaves like a mailing list. Then again, I'm only a member of about ten, so maybe I am underexposed. As for forums, there are a lot of different applications (like, hundreds, it seems) and some can be set to behave as email, others only notify, and others use feed technology (a halfway house: read all with whatever tool you choose; but only reply through site... I think; not doing much with feeds, so maybe some feed setups have a "reply" link or even form).
So, to be clear and to avoid immediate dismissal by those who prefer email, let us only discuss groupware henceforth. It's not really that big of a difference between groups and forums--we gain mailing list behavior at the cost of a categorization interface (sub-forums). As for which sort of goupware: if it must be "installed" onto a private site, I don't have much advice--I'd have to research to see which backends behave like Yahoo or Google. But if we're talking an unofficial fan list (i.e. no official support or redirection), then I'd suggest Yahoo if we prefer Calendar integration on-site (Google has it "over yonder" relative to the group site) or Google if we want easy wikification (Pages act more like a wiki--if cross-linked, of course--than Yahoo Files).

It has been said that you can configure your account to receive emails just
like a list server would do. But, can you also just reply to such emails, or
create an entirely new email to send to the "forum" list?
