KDE just created their own Lemmy instance https://lemmy.kde.social/ and I would like to see it on kbin
You just start subscribing to it. That makes your instance aware of the new instance and start pulling stuff from it.
Trying this since yesterday without success. Must be something wrong with that instance.
It’s federating with Lemmy.world
https://lemmy.world/c/kde@lemmy.kde.social
Must be something particular with kbin
add the communities you want by searching for them in the top right search option, format it like this: “@CommunityName@lemmy.kde.social”
for example. “@kde@lemmy.kde.social”
I believe federation is on my default. It only requires a user from either instance to interact with the other first.
