Dear @CTDsquaredPancancerChemosensitivityDREAMChallengeParticipants, The leaderboard has just opened for submissions. As a reminder, your team gets *10* total submissions for the leaderboard phase. You can find links to the leaderboard (and final) round submission template under the Submission Templates header on the [Data](https://www.synapse.org/#!Synapse:syn21763590/wiki/601661) wiki page. In addition, there was a discussion on the webinar today about whether participants could use Challenge 1 data in this challenge. We likely have a path forward regarding this issue but we're just waiting for final approval from the challenge steering committee before making a public announcement. I should have an update on this particular question sometime tomorrow and will notify the participants ASAP. Best of luck and if you have any questions please do not hesitate to use the Discussion forum to ask them. All the best, Robert
