I was under the impression that there was no backend support for cross-posts in Lemmy -- I thought that the "proper" way to cross-post was to click the cross post button
which would result in a new "create post" with a link to the original post, and the body in markdown quotations (which is a rather ugly solution) which, for example, looks like this:
with no reference on the original
But I then started seeing the following:
- Lemmy UI:
- Thunder:
How does one create these nicer cross-posts?
That's just the UI that shows you other communities where the same link has been posted.
If you want to create a cross-post like that for an existing post that has a URL, just make a new one with the same URL. If you want to create one for a text-only post, I think that's not possible though.
