Question about @matrix federation...
I currently have a split domain setup with #synapse where my username is amd:amd.im but my server is located at matrix.amd.im
I am going to stand up a new homeserver that uses a subdomain, but I don't whether the new amd:matrix.amd.im user will show up with a bunch of encryption key errors or be seen as a new user.
What subdomain would you pick for your new #selfhosted #matrix homeserver if you were me?
