Whoops! Please Read

Owing to a misunderstanding between Mr. Php and Prof. MySQL the leader boards we published earlier today were not entirely consonant with the actualite. The confusion arose because Mr. Php forgot to tell us that he didn't put his clock back to GMT last weekend, so anyone who submitted their solution within an hour of a deadline was treated as missing it. Luckily Prof. MySQL agreed to mark everyone's work again, and we have now published new leader boards. As a result there are actually 20 teams in joint first place on the overall Leader Board, not the 15 we advertised earlier. Sorry about the confusion.
