Actually, clicking those links actually works! Hooray!
I was under the impression that you were supposed to be able to search for "!hobbit_art@hobbit.world" in the community search bar and find things there. Now that I know it works, I've found that simply modifying the community url also works. So going to: https://lemmy.world/c/hobbit_art@hobbit.world actually jumps me right to it.
So, looks like it was already working. Thanks!
Can you clarify? If my instance doesn't have custom emojis, it's safe?
