Is this also valid the other way around?
It’s not possible or at least not for now. That’s something that has to be implemented and the devs of Lemmy doesn’t seem to be interrested in that feature. Kbin is kind of something inbetween Lemmy and Mastodon, you be able to post on Lemmy and Mastodon, but i’m not sure about the future of kbin.
Thanks, was not that much up to date about it.
