Is it possible to have multiple instances of Discourse but that users can log in to all of them with the same ID info?  
Let’s say that I have a forum for multiple cities, [city1.domain.com](http://city1.domain.com), [city2.domain.com](http://city2.domain.com), [city3.domain.com](http://city3.domain.com) but that users only have to register once.  
Thanks for the help in advance 🙂
