Seems like it, though it wasn’t actually my intention. I’m not even (planning on) using my Mastodon account much. But when I followed the MassisvelyOP account on Mastodon they followed back and I thought, I should (at least) pin a post to my Mastodon profile which references our GW2 community.

What I didn’t know until now is that referencing a lemmy community from Mastodon also creates a post in the referenced community. I thought that you could only comment on lemmy posts from Mastodon.
