The Kwant mailing list has been migrated to a new server that provides a much-improved web interface.
In May 2020, thanks to the friendly people at python.org, kwant-discuss was migrated to a server running Mailman 3. The list remains a mailing list (existing subscriptions continue), but now also offers a modern web interface that is similar to a web forum. The complete archives were migrated and are now searchable. Please see the “community” section of this site for usage information. The old address of the list remains usable: any messages are simply redirected to the new one.
