Lots of Fediverse stuff works like you might know email to work, i.e. thing@place.com, no matter where your email is hosted, you can send and receive messages from other hosts.

In this Case, the piracy community, within the lemmy.dbzer0.com domain, you should be able to copy-paste the [email protected], or any community like it, into the search bar of your home lemmy server and be able to subscribe.

Communities will grow and shape with time, but the only thing I’m really missing is some of the RES features: j and k keyboard navigation, click-and-drag expando resize.
