With the scroll-wheel of the mouse or with the left + - controller you can zoom in or out of the map. If you keep the left mousebutton clicked and move the mouse, you will also move the map.
If you found your town - or even the street in which you live - just click with left mousebutton on it, a window will open in which you can fill in your details. Then simply click on send - that's it. The entry will be released manually. In the right above part you'll find a search function for usernames. If there are further questions, please use the contact sheet.
