It is with profound sadness that we share the news of the passing of Joost Groot Kormelink, a cherished member of the Open Education for a Better World (OE4BW) community and an exceptional mentor in our programme.

Joost was a wonderful person whose kindness, dedication, and generosity touched the lives of many. As an OE4BW mentor, he generously shared his knowledge, experience, and encouragement, supporting developers in transforming their ideas into meaningful open educational resources.

His passing is a profound loss for the entire OE4BW community. His contributions to open education and, above all, the people he inspired and supported will remain an important part of his legacy.

To honour Joost’s memory, we invite the developers he mentored to share short testimonials reflecting on how his guidance, encouragement, and support influenced their projects and personal journeys. Through their stories, we hope to celebrate the lasting impact he made on our community.

Our heartfelt condolences go out to his family, friends, colleagues, and everyone who had the privilege of knowing him.

Thank you, Joost, for everything you gave to our community. You will be deeply missed and warmly remembered.
