Quel âge as-tu?

You click on their profiles and send them private messages. Introduce yourself and ask them if they're available for language exchange. I don't know if they're interested in a French-English exchange. I posted their discussions just as examples that young people also use this platform. I think most people looking for exchange are rather in their beginning 20s. People in their 20s are also young of course. For me, everyone below 40 is young....

How i can add them ? 

16ans. C'est pas pour moi ici hein ?
