Thanks for the question Mark!
Since this is a challenge and not an official contest, there are no officially published "rules".But rather, I get to decide how to do it.
For most of the weeks that there was a tie, I sent all of the top vote getters a shirt.Last week wasn't a tie at the time I checked, but it seems someone added a vote after I picked and posted the winner.Since you've never won a shirt before, let me send you one!Thanks for participating!Misty (I love that I get to make the rules) Decker
