The registration, as set up by our central administration, will proceed in two steps.

Pre-registration: Both scientific and administrative pre-registration below (form 1 & 2) should first be completed. This step is mandatory but does not guarantee registration acceptance. Indeed, the number of participants is being limited to 120. Once pre-registration is done, an acknowledgement mail will be sent to the applicant.

Registration: The local committee will choose 120 participants among all pre-registrated applicants and a mail informing them that registration has been accepted will be sent. After reception of this mail, they should proceed to payment in order to validate the registration. Please notice that: a) Payment is compulsory but cannot be made before the reception of the acknowledgement email. b) Only payment by credit cards or « bon de commande » is allowed. c) Invited speakers should not complete the registration step. However, pre-registration is necessary even for them.
