The server in general seems to be very queer friendly, here you can look at their 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 ! from your lemmy account and then click subscribe. The same for ! 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.
