Spaduf had missed it (you see it on the post on !newcommunities@lemmy.world ), and that's why the name is close while different to the point of it being confusing
I see posts like .ml and .world and I have no idea what they are even though I’ve been here a while.
In a group email, you might see people from Gmail and Outlook as recipients. It doesn't really matter that everyone, everyone can still see the emails and send them to each other.
