My real name is Sylvain beorchia. You can contact me at firstname.lastname@example.org.
I'm not an active contributor to OSM project (no enough time, no gps), but i have an eye on it since a long time. I try to promote OSM as often as i can. I did once a presentation of OSM on a GIS meeting in Paris 2 years ago (GeoEvenement 2007). I'm currently working as a GIS senior engineer in a company called Makina Corpus (OpenSource informatic services).
