That is so sad. I only just found out. Grayman was key person in the development of our game, and he helped me no end. He always had time to help new mappers. Was always constructive, an all around good guy who will be sorely missed by the entire community. His passing will leave a hole that will be difficult to fill. As someone who has lost too many to Cancer, I feel his families pain.  RIP Grayman; and Condolences to his family and friends. 😢
