If you have more than one question for M. Safar, please post them in separate threads -- that will make responding much easier.
As M. Safar's native tongue is French and as he will be writing responses from Paris, the responses will be in both French and English.
Please understand that there will be something of a lag between the questions and the responses. As an international forum, we are all living in different time zones, and not all of us are in the same zone as Paris (though some of us may wish we were)! If you are in the US, posting a question early in the day will make it more likely that the response will posted in the same day.
