For all participants (association members or not), the registration fee will increase by 150 Euros. The registration will close on 15 July at 24:00 (Paris time) and the post-deadline on-site registration will be possible only during the meeting period at the registration desk with the fee (increased by 150 Euros, association members or not, with respect to the early registration, and paid by cash) but the meals will not be provided; a limited number of meal coupons may be separately purchased on-site by the post-deadline participants.”
