Nederlands

Registratie vindt plaats in twee stappen:
1. Registreer op de wedstrijdpagina op de WCA-website.
2. Betaal de registratiekosten op de WCA-website. Pas na het afronden van de betaling is de registratie compleet.

Deelname kost €17

Zolang de wedstrijd nog niet vol zit accepteren wij deelnemers op volgorde van de aanmeldingen mits er betaald is. Als er meer aanmeldingen zijn dan het maximumaantal, dan worden de resterende aanmelders op een wachtlijst geplaatst mits er betaald is. Als er ruimte vrijkomt worden er deelnemers vanaf de wachtlijst geaccepteerd, wederom op volgorde van de aanmeldingen. Als de wachtlijst te groot wordt, dan sluiten we de inschrijving om overbodige kosten te verminderen.


English

Registration is done in two steps:
1. Register on the competition page on the WCA website.
2. Pay the registration fee via the WCA website. Only after completing both steps your registration is complete.

Registration fee is €17

When the competition has not filled up yet, registrations will be added in order of the registration time on the WCA website for those who have paid. If there are more registrations than the competitor limit, then the remaining registrants that have paid are placed on a waiting list. If space opens up, registrants on the waiting list will be admitted, in order of the registration time on the WCA-website. If the waiting list becomes too big, we will close the registration to minimise unnecessary costs.
