alternatively, to view a remote community from your lemmy instance you just append the domain to the end of the URL to indicate its on that specific remote instance: e.g. if your home instance is lemmy.ml, visit https://lemmy.ml/c/[email protected] to see the remote “futurama” community from your instance. If you remove “@lemmy.world” you’ll see your local futurama community, which isn’t very active.
