It's mostly informal, and most are ran by older (35+) trans people so try to ask around in that demo. I could ask around for you I run one myself but my people that I know are all filled up. Ultimately the best commune is the one you start.
I would say trans and queer communes are probably the largest kind of intentional community there's quite a lot but they don't advertise for obvious security reasons. There are legitimate issues with chasers and right wingers trying to stake communes out.



I love being old
