If you decided to join this instance, I just wanted to say welcome and hope you have a good time!
There are some basic rules in place but it basically boils down to being a nice person. This instance is located in the US because I figured it would be a fast location for most people.
We dont have many local communities but feel free to create new ones if you want. Otherwise you can just subscribe to any community from any instance from here as well. There is another post here how to do that.
Enjoy and have a good time!
