I have had a pretty bad time making those work. I have tried searching for them at the communities page, and removing the exclamation mark and pasting them on my instance (lemmy.world/c/[email protected]).
Some times one of those works, other times my instance finds nothing. And if I go directly to the home instance of the community, it doesn't bring my login.
They are only really useful for getting an instance to federate an off instance community- you paste that form in the search box, and usually a few minutes later you can access the community.
If you want to have a link to a community, use just ‘/c/[email protected]’ - even if the instance is the one you are on. That way it will work wherever you are logged in. example is a link to ‘/c/[email protected]’
I haven’t found a way to link posts or comments that are instance portable- if anyone knows of a way, I’d love to hear it.
This is one reason I don't use Kbin - it seems to have pointlessly chosen its own terminology just to distinguish itself from Lemmy which makes it less useful.

Yeah, those don't work from kbin. None of the links I've found in c/newcommunities works for me. Am patiently waiting for whatever the problem is to be resolved.
