I autotranlated that, and it sounded interesting. I agree that for this app it makes sense to start local, to get enough matches.

Where are the most common vacation countries abroad from France? It may be good to add more languages for international trips. My recommendation is to add an English translation and post again. [Hi from Argentina! Most people here know something and English, but there is a lot of variation in something.]

Feature request?: Perhaps show in the front page the cities of the match requests to encourage people to sign in?
