That's what I'm wondering as well. On which platforms? Group chats? Discord? Discourse? One I've never heard? I ask because I've been flirting with the idea of having more closed off groups, playing with using Discourse for it, as it's a self-hosted platform and I can tweak plugins/themes and close it off to the public. But I'm open to others, and more so, really just curious to learn about some of these communities, how or why they've chosen the level of exclusivity/inclusivity that htey have, etc.
