Hi, everyone should attend the opening speech on site and after that you can work from anywhere you'd like :) To ensure that everyone who stays on site for the FULL duration of the jam has a dedicated working space we had to limit the capacity to 100 people. However, we know the interest is great and more people would like to participate, we have the extra 50 spots for people who still wanna join even though they don't have a guaranteed working spot on site. The second limit of 150 poeple is there mostly to ensure that our judges will be able to play all the sumbmissions and fairly evaluate each of them to pick the finalists and the overall winner.
