The conference fee payment is handled by UIK. Please visit the dedicated UIK webpage of the workshop, where you have to click "Enroll" and then register in order to pay the conference fee.
During the registration workflow you have the option of adding accompanying people and select options from the social program for them, but also to let us know about dietary or any other special requirements.
We would appreciate if you inform us about participation in the various activities (during registration; can also be updated later on), for better planning. This does not affect the conference fee for participating people, as that one is "all inclusive", but it does affect the price for accompanying people.
