On a more on topic note: Lemmy is small. We dont have the population to warrant that specific of a community, yet. I’d recommend starting by joining a community about vinyl, making posts about vinyl care, and seeing how they do. When you’re taking up a significant percentage of a larger parent topics feed, I’d say it’s time to splinter off
I’d just add that we run the risk of being extremely unappealing if we have too many communities with near 0 activity. We’re better served at the beginning having fewer, more general communities, to attract critical masses
