Just found something new:

Did you put a complete village or even a complete city on the map and you want to check the changes people make to "your" area? You can do it with an owl:

Zoom to your area and see the changed areas of the past 24 hours. At the bottom left of your screen there's a link to create an RSS/ATOM feed of your area. That way, you can always check other mappers in "your" area (and thank them if they upload/correct something) :P

Happy mapping.
