For anyone who didn't see before, because m.s is busy being largely defederated, and my account there never actually got the traction I thought it would after initial promise, I'm moving notifications here. I will still boost them on my old account, but it's clear that this is closer to the audience I want to reach.
Also, I found the "issue" in the code that kept me from inaugurating this w/ something better: apparently it now refuses to post more than once for some instances' rules compliance.
