On another Lemmy instance, I saw that I was not logged in but could subscribe by putting “!emulation@lemmy.ml” 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?
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).
Wow, thanks, that helps a lot!
