Hi,
Back from said event, I can also testify that French was in the language pot
...but more importantly, that we achieved remarkable engagement with the public this year, and of a very wide age span.
Also, more details will follow, but since this is a forum post encouraging to attend, we at the booth were struck by the high number of forum members and contributors who showed up to meet us "organically" this year, take on discussions or even bring their own demos along.
Cheers to a beautiful collaborative project, and to the event.
