Will the latest mailing list contributions be migrated to the Archive?

As far as I can see, part of the mailing list has already been migrated. As of now, the latest post is about a month old, i.e. from the beginning of December 2019.

What happens to the posts between Dec 1, 2019 and Dec 31, 2019? Will they make their way into this forum?

You ve seen the Fayes mails?

Yes, the archive will be imported this or next week.
