I believe links like this will be sorted automatically in Lemmy 0.18 but until then links are like this without the space between ] (

[!community@instance] (/c/community@instance)

!kde@lemmy.kde.social

Currently if the community hasn’t been discovered by your instance then you’ll get a 404 error like I just did, apparently it’s a known thing and you need to search for the community before accessing it, see here - https://github.com/LemmyNet/lemmy-ui/issues/1335

I am on lemmy.ml and that properly shows up as a link for me. Weird that it doesn’t work for you even though we’re both on lemmy.ml.

Before you had to fiddle with the markdown link manually. As of v18, you can just type out the name of a community in the !name@instan.ce format, in plain-text, and it will become a working link.
