Hi. My name is Johnny.
I am a big fan of Google Earth. If a Wikipedia article about a place specifies the coordinates of its location, a link to that article will appear on Google Earth when viewing that place.
So far, my only contributions to Wikipedia were tagging two such articles with the coordinates of the places they are about.
To learn how to properly tag a Wikipedia article with coordinates so it will show up on Google Earth, see this page in the Google Earth User Guide.
