Not really a support question.

More a ‘this does seem to work like it should be if you do it that way it does work’ thing;

I checked out a Lemmy instance, in this case lemmy.world , and there seems to be some interesting content there.

It is possible to add this also here so it shows up in the Friendica GUI. But it does not seem to work like it is instructed to do so.

Example;
lemmy.world/c/linuxmemes

When you press on the button ‘subscribe’ you get a popup asking for the name of your external instance. Should be ‘friendica.world’ . Error.

walter.friendica.world , walter@friendica.world , etc does not work.

But there is also a text saying to put

in to the search function of your instance. That does not work also.

What does work is;
Go to the ‘contacts’ section ( friendica.world/contact )

Use the ‘Add new contact’ function. Put in that search field ‘linuxmemes@lemmy.world’ without the ! and the ‘’.

And that Lemmy discussion forum is added.
