[Answered] How do I subscribe to communities of other Lemmy instances?
On another Lemmy instance, I saw that I was not logged in but could subscribe by putting "[email protected]" into the search field. However, when I put it into the search field of this Lemmy instance, it gives me a comment containing that string, but does not allow me to subscribe.
Easiest is to just search the URL of the community. In this case search for https://lemmy.ml/c/emulation using your instances search tool. It seems to work even when the !community@instance syntax fails to find the community.
Optionally you can write the address by yourself using yourinstance/c/community@otherinstance as the URL. In your case that would be https://lemmy.world/c/[email protected].
Thanks, that helps me for this. Is this a general way? So I don't put it into any search bar, but just write https://lenny.world/c/(everything without !) or is the emulation community a special case?
That's not the official way but that's how the URL for communities looks like, at least currently. If you want you can automate that with a bookmark on Firefox: https://lemmy.world/comment/332210 (see also my comment there about %S vs %s).
What you are doing is right, but it takes some time for your instance to set up the connection to the new community. Give it a few minutes, then search for the community by its plain name (e.g. emulation) under all.
