Of course, we do everything we can to ensure that everyone gets to play what they want, but it can happen that some events become so popular that everyone simply can't get a place. If this were to happen, the order in which the payment reached us applies.
If you are not allowed to play due to, for example, a lack of referees, you will be refunded the registration fee for the event in question. Via the web, it is also possible to see if payment has been registered and which arrangements with pre-notification requirements have been entered into.
