I'd like to let you know that we are trying an experiment with the TC this year.
We are working on the rules in the open on GitHub. As GitHub is a nice platform for collaboration, we would also appreciate any rule change suggestions you may have until the 11th of December, 2017. Note that we are not looking for big changes, but rather more subtle changes that can still improve the Soccer games in many ways.
