The official™ information, provided by the infallible legend that is Keith Dunn (and the Mastodon bot that will relay his tweets)
Did a tremendous job of providing updates and useful information last year: Taka Does Stuff and Anna.
And also caretakers of The List™. This is probably your best bet on the most up to date info.
Since Keith is now on Bluesky, the hashtag is also there: #bm100, the old horrible, horrrible network got even more horrible but I think there are still people there: #bm100
