I believe the last task related to this email list transition is now complete, which is that the URL
https://lists.p4.org, which formerly went to the web site for managing the old Mailman email software, now redirects to this page, which if you scroll down a little bit shows a list of all P4.org email lists and how to join them:
https://p4.org/join/
I have confirmed that for all of the email lists that were created for conversation of one of the P4.org working groups (language, architecture, API, applications, education), all of the working group chairs are owners of those email lists.
If you wish to contact all of the current owners of a P4.org email list, add "+owner" to the name of the email list. For example, to send a message to all owners of the
p4-...@lists.p4.org email list, send your email to the address
p4-arc...@lists.p4.org
