pfr I know that the IRC channel doesn't get a huge amount of traffic, but I wonder if we could possibly move #UnitedBSD from Freenode to Libera.chat ?
THe IRC channel used to be very lively at a time when the forum either didn't exist, or was more generally oriented towards *BSD deskop computing. Like a UnixHub for BSD to give you an idea. At the time, the FreeBSD community was facing a difficult moment, due to some divisive choices from the project, the drama brought by the introduction of the very criticized former CoC, and the influx of a bunch on trolls on the official forum: this made UnitedBSD more attreacting to some users. Later on, after moving over Flarum, and losing part of its former userbase across the migration, the focus of UnitedBSD shifted towards NetBSD and OpenBSD in this order, possibly attracting some traffic from DeamonForums, whose community was mainly on OpenBSD and NetBSD.
Within the last few years, the activity on Reddit and Matrix has grown exponentially, and this imho substracted some attention from things like IRC, mailing lists, forums, not to mention the newsgroups on comp.unix.bsd., which have become completely dormant in the last years.
This is just just my very opinionated persepctive.
