It is with great emotion that I announce the passing of our Marcus. Everybody knows here how much he gave to this community. He has been important for me, and for many young quantum-gravity enthusiasts. I learned the first things about loop quantum gravity thanks to him. He had an unique acute and sweet way to put everything. I loved it and I hope I will always bring it with me. And I loved and used this thread that he started. I hope we will keep it alive, in the spirit he made it.
