Currently NT instances are not joined together but that is a planned feature using the Fediverse and ActivityPub. Probably the best place to find info is the Github if you scroll down to features, or to ask me in the Discord (also linked on Github). The Readme is super incomplete missing a lot of information on a lot of features but I'll probably have a chance to take care of that tomorrow. Thanks for the interest and yeah that's a classic Bill Gates video had to upload it ;)
