Except for the earliest challenges, my first was August 07 and I participated in nearly every challenge, except for two, until the start of this year, when I only participated in February and June. I've always tracked the progress for all challenges, in that time, however. So most of these numbers I'm already familiar.
I can almost tell you, who was in second and by what margin as well, in every challenge I entered, and others too.
That November 07 challenge, my first win, I was the only entry until the last week of the month, I felt it might have been a sullied win, as the only entry, then RobA entered and gave me some competition. Still, my favorite win was in September 08, because it was the largest number of entries in guild history so far, and lots of voters - with so many great competing maps.
I'm so glad that the Challenge has really grown and become an anticipated feature each month. In the early days it seemed to struggle for attention.
And since only four (?) challenges have been sponsored with prizes, I'm proud to having sponsored two, as proud as I am of my wins.
