a simpler workflow :<br>
give a part to each one<br>
load the gpx trace with the editor of your choice<br>
simplify and connect it to the concerned ways, add tags<br>
upload the new ways into osm.<br>
some will say you may send the trace too.<br>
once finished, delete the trace of your computer<br>
or move it to a "done" directory<br>
<br>
and so on with the next trace until you finish your part :)<br>
