Since last week there is a website available, which is able to display how you contributed to the OpenStreetMap (OSM) project: http://hdyc.neis-one.org

Today, I made some small updates. The picture below shows the changes in the website. First (1) I imported the new planet data (Planet Dump 09/15/2010) that shows you on which OSM objects you are the most recent modifier. *NEW* is that the timestamp of your first contribution to OSM is displayed (see (2)!), further a link to your first OSM Node is attached (3).

How did you contribute to OpenStreetMap ?

So: “How did you contribute to OpenStreetMap?” Use your UserLink and share it with other OSM members (3) … 🙂
