At work we have a quiz tournament via
this site - only 10 questions a day and you get to choose a subject (our quizmistress chooses subjects so we spend a week on each Dewey section so this week it's the 800s - literature) and there's leader boards and virtual prizes and everything. Would anyone be interested in this? It's not much work for the quiz mistress as if you forget to change the subject, you just carry one with the previous days' until there's a mutiny...
