Hi Markus,
I plan to attend but I'll probably work on MongoTalk/Mongo-Voyage that day.
Do you have an address that we can enter in GPS/Google Maps?
Inria
40, avenue Halley
59650 Villeneuve d'Ascq
France
But google map is sligtly wrong placing the dot. It's a bit up the street (see the label).
It will be likely in Building B (across the street). I will later send a mail telling
you what to do when you arrive (as the Building A has a reception but B has
not...)
