I’ve got a couple groups of friends that my wife and I play Jackbox with over discord, it’s almost as good as being in the same room!

Yeah, I found it completely by accident

I started using Lemmy/Jerboa two days ago and have been able to navigate to communities outside of my instance while staying in the app. Maybe it was a recent update?

I agree about the missing quality of life around comments and the inbox, but in what way is subbing to communities from other instances difficult? I’ve just been typing keywords into the search bar and have had no issue subscribing to any communities, no matter what instanc they are hosted on.
