It would be nice to have a category in the forum synchronizing with Usenet’s comp.lang.ada.
I found it should be possible using this gateway: GitHub - sman591/discourse-nntp-bridge: Discourse plugin to keep NNTP & Discourse in sync
Unfortunately, currently not in a known deployment: Still supported? · Issue #33 · sman591/discourse-nntp-bridge · GitHub
Running a spam filter would be indispensable.
