Hi all! @Rebecca Courtney Please, could you help me with this doubt. What is the role of the Decisor in exercise 3 concept (when she/he has to sketch the solution), does she/he also have to do this exercise or does she/he only vote for it at the end of Day 2? It is a bit confusing for me because in the tutorial video there are 4 participants, but only 3 solutions are shown, so I had this doubt.
