I'm very happy to announce that at long last, the main GNU Mailman mailing lists hosted at python.org are now available on Gmane. This includes:
mailman-announce mailman-developers mailman-users mailman-i18n
All of the archives for these lists have been imported as well.
If you're not familiar with Gmane, I strongly encourage you to take a look. It's an amazing service for the free software and open source community.
While web archives are available, for me, the NNTP access is the really cool thing. If your mail reader can speak NNTP (the good and still useful part of Usenet :), then you just need to subscribe to the newsgroups and you can read entire threads of discussion from the past. After the first email verification dance, you can even post to the newsgroup and it will show up on the mailing list.
I'm on a personal mission to stop archiving any publicly available mailing lists, and what this means to me is that I can just about halve my inbox! Here are some links:
The NNTP interface is also a model of what I'd love to see Mailman 3 eventually provide by default (not to steal any thunder from Gmane).
My thanks to Lars Magne Ingebrigtsen who runs Gmame, and to the python.org postmasters for all their help in getting this set up.
