Thank you, this is going in the right direction. Using this trick I uploaded a sample GPX with a single waypoint (a post box in London): http://www.openstreetmap.org/user/AlexandrosPapadopoulos/traces/981138 I then follow the "edit" link from the "Your GPS traces page": http://www.openstreetmap.org/edit?gpx=981138 This brings up P2, but I can't find my waypoint. Following the "GPS data" -> "My tracks" pulldown menu and selecting "Load" for this gpx again doesn't seem to do much. Stuck at this point.
