With your contribution we pay costs such as room hire, travel costs, hotel accommodation, translation services, promotion and other expenses we have to organise our events. If you would like to contribute more than the minimum entry contribution, then you are welcome to. You can determine your own contribution in your personal capacity. We kindly refer you to the fees you can choose from on our online registration form. A percentage of the income that remains after deduction of all costs goes to charity. Any contribution is welcome.
