The server in general seems to be very queer friendly, here you can look at their communities. https://beehaw.org/communities
And i think many more people should join their awesome communities. <3
for instance, in this post the admins describe the desire to create a server which is very friendly/non-toxic and i like that.
if you want to subscribe from another server, you can search for !firstname.lastname@example.org from your lemmy account and then click subscribe. The same for !email@example.com or other communities. basically, what @username is for users, !communityname is for communities. (And because i did’nt use auto completion for the community names, it show up as regular text, and not something you can click on.
