Recently, I tried to upload a Google Earth file for the benefit of a group of riders doing a ride in Baja and an inmate was having trouble opening a .gpx file as he didn't have the software to look at it. Since I have the ability to convert the .gpx track to a GE file, I did and attempted to upload it to the thread. The upload window allows an upload of a GPS Track, but when I tried to upload a .kmz file, then a .kml file I was greeted with "The uploaded file does not have an allowed extension". I believe there are more users of Google Earth software on this website than others that have paid for software, such as Mapsource, Basecamp etc. Allowing the ability of uploading both kmz and kml files would greatly benefit and enhance this websites users experience. I'm hoping the moderators will consider changing the restriction imposed so that a greater number of inmates can benefit.
