HI @yanirmr Thank you for your submission. I had a look through your notebooks, and I appreciate you providing one for the three main components of this data collection. On the basis of those drafts, this is ready to move forward. One thing that we will ask you to include in at least one of the final notebooks is to provide at least one community challenge: an unanswered research question or an unsolved problem that you think could be addressed with your data. That can be purely narrative, and need not be solved by you.
