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?
/r/guitar gave a great example of everything not to do in an online guitar enthusiast forum, at least from a mod perspective. You won’t find that bullshit at /c/guitars as long as i have anything to do with it, we just vibe and talk shop.
