Gmane (which I'm using, and actually posting this message through) carries debian.user as a newsgroup. Decent newsreaders provide sophisticated features for filtering messages. For instance, I'm using gnus, which can score articles. So, I'd say: * learn a good newsreader * find debian.user as a newsgroup (gmane or otherwise) If you really want to use mail, mutt is powerful enough to score messages, and thread them, too.
