As a side note, how do people handle HTTPS with private networks (VPN or local) these days? I typically just stick to HTTP, but it would be nice to get rid of the warnings/lock (and I use HTTPS-only mode and firefox seems to require a fresh exception for every port).
I was just thinking that common forum software implementing ActivityPub would be a great way to link all of these disparate web forums that are still active and have useful content.
