Hi Gunnar,
For now the forum and mailing lists will co-exist, although we are focusing on making the forum the main place for people to gather and ask questions / discuss topics. We encourage everyone to start using the forum, and down the line we’ll consult with the various lists (there are several in addition to ansible-project) on ways to retire/migrate them.
In the meantime, if you prefer the way mailing lists work, there’s a Guide to interacting with the forum by email.
Cheers,
Carol.
