Easy, first, আপনি get 1, 2 অথবা 3 of your বন্ধু to connect with, and if আপনি want to host go to Copper and ask him to open the gate. Then don't do anything until your বন্ধু come over. অথবা if your বন্ধু want to host then say to Copper: 'I wanna go out' then it will look for a town. Then it comes up with your বন্ধু character name and town, then আপনি press 'I wanna go there'. But that's for DS. And if আপনি are still working for Tom Nook it won't let you. Hope I helped!
