TIP 16: The number of places in some workshops is strictly limited, so arrive early to avoid disappointment Details on how to sign up for Workshops is given in the final programme and on the Conference App. When the maximum number has been reached, the door will be closed, and there will be no further admission. We do ask for your cooperation in respecting the wishes of the Workshop Organiser, and not creating embarrassment for the student helper, whose task it is to make sure numbers in the room are not exceeded.
