I see that you are an active openstreetmap editor in Luxembourg. I am organising an OSM meetup on saturday afternoon on the 11th of June. This is an opportunity to meet with others and discuss recent mapping activities and future mapping plans, and usage of existing and potential open data. We'll also demonstrate some specific map editing procedures for those unfamiliar (and a bit shy) with the OpenStreetMap editing software.
All curious, potential OpenStreetMap-ers as well as veteran mappers are welcome. We also welcome anyone from outside the Luxembourg area to come and meet with us. Discussion will be aided by delicious coffee, or other snacks and beverages available at the venue.
Can you please tell me if you think you'll show up so that I can find an appropriate place?
I look forward to meeting you.
