Anything else: "Sarah linked to the wonderfully named Licence To Krill, a trivia team raising money for 826CHI, an afterschool education program for disadvantaged kids (they run the Boring Store in Chicago, and 826 also runs the Time Travel Mart in LA and various other fundraising shops around the country). The team needs to raise $500 for the cause in order to compete, and are friends of friends in my nerd community so I think if they can get in they have a chance of doing very well."
