Thanks, seems to have worked well! And I'm thinking this tool will help a community's posts better show up in ALL streams, which can be a surprisingly helpful way to get eyes on it IME.
I also see some pretty major instances seem to have opted out, such as Lemmy.World, Sh.Itjust.Works, Europe.Pub and Quokk.Au. That's disappointing, and I wonder what their deal is?
