+ Nintendo = MapWii.com
MapWii.com allows you to map your Nintendo Wii's number, as well as view others who have done the same. When you see someone you want to add, simply click the "Request" button on their map marker and your friend request will be sent to them. Over 6000 Wiis have been mapped worldwide, with hundreds being added daily. It is optimized for the new Wii Internet Channel, but also works great with regular desktop browsers.
