@charlyblack Yay! Thanks 
@charlyblack I wonder why they're called domains rather than instances?
@squaregoldfish domain is technically more general but the two are basically interchangeable here, I don't know if there's a specific reason for choosing one for the other, maybe 'domain' is more widespread in the extended federation..
@squaregoldfish it is! from the burger menu in the user account page, you can hide the whole instance it belongs to
