If you already registered for MIR 2020 or 2021, you can keep your spot for 2022. See email that was sent out on March 31, 2020 or March 29, 2021.
Filling in the registration form and submitting the information does not guarantee that you will be able to participate in the Rally, nor does it guarantee the room type you select for the accommodation at the hotel. Participation and room types are both subject to availability at the time of submitting the form. A manual confirmation will be sent, once the registration has been processed.
Registration for MIR 2022 will open in October 2021. Welcome back then!
