Congrats to Frank! (Check your private messages for info on collecting your prize.)
And just as an illustration of how good his odds were, Frank made about 50 posts during the contest period, so his odds were about 1 in 48. Better than buying a lottery ticket! Cheaper, too.
Good luck to everyone in the 2nd contest period! The next draw will be on December 18th (or thereabouts -- sorry, I was a little tardy on this one).
