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.
What is the correct way to do it?
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].
