Dear participants, **Registration closes on September 7, 2026.** By that date your team must be created and registered for the challenge (single member teams included), every member must be individually registered as a participant, and every member must have sent us the signed challenge rules. Registration steps are in the wiki, section "How to Participate". Two clarifications on submissions: 1. All submissions must be made on behalf of your registered team: in the Synapse "Submit to Challenge" dialog, choose "I am submitting on behalf of a team" and select your team. Submissions made as an individual are not considered for the ranking. 2. Only the best submission of each team is shown on the leaderboard. If you are unsure whether your signed rules were received, contact us. The CLiMB 2026 organizers
