"Dear Erick, Didier and I want to thank you and congratulate you and Philip once again for your efficiency, availability, and your professionalism, which you have always shown with a smile on your face and in jovial mood. We receive many congratulatory messages and that makes us really happy. Both the participants and the speakers loved the place. No one noticed all the little hassles that you managed perfectly.  All was perfect, really.  It is great working with friends when they are as competent as you are.  Thank you again and well done! Kind regards, Olivier et Didier."
