The groups are determined by chance
To get a large group of participants going and prevent cliques from forming, a random division into workable teams is made. Upon arrival, everyone is issued a badge at random with a text or colour indicating which team they belong to. Subsequently, large boards indicate with which workshop each group will start and from then on, people are referred to each successive item on the programme. Some groups will develop strong bonds, others may fall apart because team members quit and join another group. Anyone is free to choose.
