We float around a lot, right now I think we're most active on Amino with Kinmunity and TG being close seconds. We might also go onto Tumblr from time to time and go through the otherkin tag to see if there's anything good. We're also in some fictionkin and plural Discord servers.
I have my own soulbonding forum, thats it. There is a dreamwidth community now, but its not active. My forums not active anymore either, I just have no other places to hang out. Theres also the fictionkin forum, but its pretty dead too.
I've... been around a lot of 'kin communities but never really stuck with any except KM, for one reason or another. Many years ago I was really active on TG, but I've heard... bad things about the new management over there so I'm hesitant to rejoin. I'm also on the Daemon Forum and tend to go through phases of being really active there (same with the Discord chat associated with that forum). Outside of 'kin/plurality things... you can pretty much always find me on Flight Rising's forums! I am way, way too active on there. Like, too much. It's a problem.
I’m active here and to some degree on Werelist as well. I own my own forum but it’s been dead for a few years since it wasn’t particularly active and I never had anything to post. I still don’t, really, but I try to come up with things every now and then.
At the moment, I'm most active on Amino, here, discord, and Tumblr.
I've joined TG and Werelist, though I never really stuck with them and quickly lost interest. Knowing me, I'll check up on them after a while, but probably won't be very active whatsoever.
Time to elaborate on my previous post! My soulbonds and I have started getting back into an adult role-playing chatroom again. And I'm active on Discord but mostly on my own server. I also sometimes appear on Pokémon Showdown for a short period of time.
