Unlike other challenges, you don't get a trophy just for participating -- you have to actually find primes to win something!As with last year, we will be awarding special "jersey badges" to the winners in four different categories. This year, we're also offering special badges that are available to anyone who finds an eligible prime!Come join us in February. More information about Tour de Primes can be found here.
