New registration link for Azur colloque

3rd august 2023

Azur Colloque has updated their system and recreated our login page, to correct a bug that prevented several participants from successfully completing their registration (apologies!).

The registration link has changed in the process and has been update below.

Important points:

  • no on-site payment (cash, VISA, ...) will be accepted;
  • fees must be paid exclusively via Azur Colloque;
  • online fee payment cannot be cancelled nor modified;
  • conditions for reimbursement are directly set by the CNRS (only medical circumstances can call for a case by case review & consideration), and the local committee has no saying on the matter.
