FYI: kbin.social has a dark mode (I just discovered this--maybe I'm late to the game), see image for simple how-to... (media.kbin.social)
/m/ShareYourMusic - Calling any kbin musicians! Come share what you're making! (kbin.social)
I don't know where to share/promote new communities, exactly, but if there are any musicians moving over from Reddit, feel free to come share what you're making/what you've made....
