I've created a couple of pages off the Mailman wiki:
http://www.zope.org/Members/bwarsaw/MailmanDesignNotes/FrontPagefor collecting unofficial patches. SourceForge's patch manager is fine for managing the patches (uploading, updating, describing, commenting on, etc.), but really lousy for collecting them. I need to start closing patches which clearly aren't under consideration, either because they're against MM2.0.x, or because I'm pushing them back to a future release.
The wiki pages should be used to describe the patch, and may include a link to the SF patch manager, or to some other location containing the patch (you could also add the patch to a sub-wiki page).
SourceForge links will be fine even if the patch itself is closed. Anybody can add patch summaries to this page, although I may go back later and edit them. Please do /not/ add patches to the wiki in-line, that'll just make for an unreadable wiki. Please /do/ include an email address that users of your patch can contact you with.
I've seeded the pages with a link to Richard Barrett's ht://Dig patch, for which he's included both a MM2.0.x and an MM2.1 patch.
