The way Lemmy works right now is you search a community in your instance for it to then get shown, so you need to first discover that community from elsewhere. With that in mind, what are some growing communities that you discovered that could get some more love?
Self promoting https://midwest.social/c/synths (like /r/synthesizers) and the hubby’s community https://midwest.social/c/guitars (like /r/guitar) for anyone interested in those.
