[Mailman-Users] Human orinted interface

Hy again!

I have absolutly no idea about mailman implementation. I found great the
interface and to use python to do the job. And now my system administrator
install it. In the meantime I use a path with procmail to do the job in my
personal account. Some users (multiple lists subscribers) suggested me
that it is desirable to receive only once crosposted messages. So
yesterday I organised my patch as a person list and for each person I have
a list of subscribed list and I do the posting accordingly to that list. 
It is completly person oriented. But it is a simple provisional patch and
I hope I'll be able to use mailman soon. I strongly hope one day mailman
will be able to do the same. It sould work with one person database only
without all the terrific staff you told me (sorry if I completly
misunderstand how mailman works, I never imaginated it was so complex). 
It could be essential with an ombrella list organisation as suggested
yesterday on this list. It is very desirable for user with poor internet
link (I have a lot of subscribers in southern contries). I have a dream to
install a e-mail to fax gateway so multiple posting of crossposted
messages could be problematic.

Thank you for information and special thanks to the programmers to allows
people communicate with such a beautifull tool.

See you,
