We have sent out a survey to the RB community regarding the selection of interesting RB “dropout” and “buildup” events and we will discuss the survey results. You are also welcome to propose potentially interesting events relevant to our “dropout” and “buildup” challenges. At last, we will wrap up and plan for future FG activities.
