It does sound like something requiring my ISP involvement.  I'm sure 
they won't mind if it's a one-time setup and they understand what I'm 
requesting.  The thing is that I don't really understand what I'd be 
requesting, or why.

foo-list is the name of my mailing list, and moderator at example.com 
would be the moderator's email (aka, my email address).  I'm asking 
them to create an alias for the list name?  Or should that be the 
full list email address (e.g., foo-list at lists.sonic.net) ?

What is "foo-list-moderated"?  I'm guessing "| mailman post foo-list" 
is some command line syntax that any server running Mailman would 
understand.  I can pretend to understand that (since my ISP tech 
support will probably understand it).

This suggestion was in response to my leading paragraph, not any of 
my 4 issues,so I'm not really sure what this buys if I were to get my 
ISP to do it.  Was this a suggestion for how to do the redirection? 
(in which case, I'm already good, as I already use my email client 
for redirection)

Maybe there was an assumption made that people generally don't click 
reply to a digest (since the subject would be wrong, and the quoted 
text would be excessive).  It does happen.  For some, it's easier to 
click reply and change the subject and then trim the quoted text 
(there are a few times when they forget to do the subject change 
and/or trimming, but those would be rejected anyway).

I tried this once, and I felt really really uncomfortable with it.  I 
kept looking at the To: to make sure I wasn't sending it to someone. 
The admin email says to click reply, but when I click reply, it 
addresses it to the list owner (e.g., 
foo-list-owner at lists.sonic.net), so it just comes back to me.  I'm 
not sure where it was supposed to go, but I'm also not sure I would 
feel comfortable with this method anyway.  I can picture me doing 
this some night when I'm running on 2 brain cells, and sending the 
list password to some random email.

Okay, this is bizarre. I just went to our web archives, and they now 
have the formatted "previous" and "next" links, as well as HTML links 
within the body.  I swear the other day I was staring at plain text. 
The footer has changed to "This archive was generated by Pipermail 
0.09 (Mailman edition)."  I looked at the footer before, and it was 
completely different (no mention of Pipermail).

[looks again]

Okay, I think I know what happened.  I clicked on the "Gzip'd Text" 
link, and when you do that, it shows the archives in plain text.  It 
seems kind of obvious now.  I guess that was one of those nights I 
was running on minimum brain cells.
