Register In Time!

On-line (“virtual”) conferences like ETS21 do not have the equivalent of “on-site” registration that you might be used to at in-person (“non-virtual”) conferences, where you could show up unannounced at the registration desk ten minutes before the start of the opening session, pay, and still get admitted.

Access to ETS21, Workshops, and TSS21 will be granted only after we have received proof of payment of your registration fees. Depending on the form of payment there might be some delay between when you make the payment and when we receive confirmation from our financial department that your payment indeed has arrived. Therefore, do not miss anything at the start of the conference and complete your registration and corresponding payment well in time.

Registrations and the associated payments are handled by the Conference and Event Office of KU Leuven. After your payment you will receive a proof of payment.
