Cool that I was able to post a new topic in a #Lemmy community just by posting with an @mention of its fediverse actor; @flounder@lemmy.ml
But I note that the @mention in the first sentence wasn't included in the topic title, which ended up as;
"TIL that has a Lemmy community"
I guess I could try to fix that by editing the post?
EDIT: that worked, and instantly too! Great stuff @LemmyDev and @Mastodon! Compatibility has improved a lot since Lemmy started to openly federate.
