**Celebrating COS Ambassadors and New Opportunities to Engage** Over the years, the COS Ambassador Program has played a vital role in advancing open science. We are immensely grateful to our ambassadors—past and present—for their dedication, enthusiasm, and contributions. From spreading awareness about open scholarship to creating valuable resources for the research community, your efforts have left a lasting impact. As part of our ongoing efforts to refine community engagement, the COS Ambassador Program will officially sunset on February 19, 2025. While this chapter comes to a close, we’re excited to offer new ways for you to stay involved and continue contributing to the mission of open science.
