I'm new here as an tracker, but created an account here about a year ago.
Recently moved and invested in a Tomtom GPS unit with Map Share, that lets you edit details about the map and upload it to Tomtom. Now I wanted to make some of these changes available to the OpenStreetMap project.

For the tracking purpose I use my Nokia N95 and the Nokia Sports Tracker application, that have GPX export functionality. This works great.

After tracking some small uncharted roads around my apartment, I started editing the OSM map. Some of the editing I have done evolve creating new roads, deleting some (on map, but no longer in reality) roads, changing one-way streets and types of roads, I now have a good sense of how it works.

Now I just need to find a navigation application for my N95, that uses OpenStreetMap. :-)
