I just joined OpenGeofiction and I don't really know exactly how to do things! How do you make a city? I tried to make one, and it didn't work. Also, how do you keep track of where you are working? If I am working in my city, how do I leave the website and then remember exactly where I am? Also, how do I name my city? I learned the basics of OpenGeofiction, but when I tried to do the walkthrough it wouldn't work. Can somebody help me, please? Thanks!
