note for lemmy newbies: This is !anarchychess@lemmy.ml which is completely separate from !anarchychess@sopuli.xyz. Users from both instances can post on both, as long as the two servers remain federated.

The canonical URL for that community is https://sopuli.xyz/c/anarchychess but it can also be accessed at other URLs on other lemmy instances (such as lemmy.ml, where @alehc@lemmy.ml and I are posting from) at https://lemmy.ml/c/anarchychess@sopuli.xyz

To find your own instance’s URL for a remote community (which is necessary to subscribe and/or post to it), instead of manually editing the URL to change between the two formats above, you can also paste it in your instance’s search box and it will resolve it for you.

If you want to link to a community an instance-independent way (so that the link will work on all instances where people might see your comment), you can make it a relative link like this: [hey, checkout anarchychess@sopuli.xyz](/c/anarchychess@sopuli.xyz)

… which will render like this: hey, checkout anarchychess@sopuli.xyz

(Relative links like this should work on any Lemmy instance, including the one the community is hosted at, but will be broken on some other ActivityPub-enabled sites…)
