I am sad to inform you that today Krzysztof Machocki (user:Halibutt) has passed away. With his passing our community loses a brilliant and passionate Wikimedian and Wikimedia Polska loses a valued spokeperson. But what is the most important - many of us lose a beloved, beloved friend.
Krzysztof was known for his joy and passion. For his faith in how Wikipedia makes the world better. We lose him but let us not lose that faith.
There is a memorial page on Polish Wikipedia. You can leave your condolences there and we will give them to Krzysztof's family.
