My name is Asier, and I am a member of Librezale, the Basque team in charge of Mailman's translation.
We have the Mailman localization a bit outdated, the last version that we translated was 2.1.3. I intend to update it, but now, looking at the several sites that give information about the localization process and at the messages of this list, I see that I have two options:
1. Update the last stable version, 2.1.14, using the usual way. 2. Wait and see if the localization process is finally managed in Launchpad, and translate the 3.0 version there.
What is the best way? Any hint about when the migration process to Launchpad will be done?
