So, a charity I will not name (but its initials are CCF) was sent $17,000 from a GenCon charity function to feed starving kids as a memorial to Gary Gygax. This charity, which I still will not name (but it rhymes with Brishtian Bildren's Gund),
turned down the money because it came from roleplayers.
