The Organizing Committee would like to inform you that: 1. The fee you paid is of course valid for the new date. If, unfortunately, you will not be able to attend in the Congress in August next year, you can cancel your registration under the general conditions; 2. The program of the Congress generally remains unchanged. If in the course of this year someone wish to give up or update the structure of her/his panel, please let us know. Some reshuffling will be of course possible. All important announcements concerning the Congress will appear successively on our website and on Facebook.
