Our very huge thanks go to Paul Boddie who did the amazing conversion work, almost single-handedly reverse engineering the Confluence dump through several iterations.
Hurray! Well done. Can you publish the dump somewhere on your site, or on archive.org? WikiTeam is very interested in Confluence dumps, any writing/braindump/code on the matter is very welcome. https://github.com/WikiTeam/wikiteam/issues/108
With this conversion, I am happy to say that GNU Mailman is finally fully hosted on free software.
