Some of you might have noticed the “Challenge bar” which has been on Stall Catchers’ VM for a month now 
What is it doing there ?! Well, counting the progress towards our next big milestone! Currently that is completion of the Validation Study !
All about it is explained in our blog post here.
The challenge bar is counting the vessels we need to annotate to get through the validation study - we are trying to determine the best way to calculate the Crowd answer for each vessel, and to officially demonstrate how good the Crowd (YOU!) is
The original plan was to run the challenge for 30 days, but, as explained in this blog post, the challenge bar kind of ran away from us, and a few days ago we realized we are not as done as it was suggesting! 
So we had to turn it back a little, and to compensate we extended the challenge to run for another 30 days, leading up to Xmas With Xmas bonuses coming later on! 
Stay tuned for that one!
HINT: at any time when a challenge is active, you’ll be able to learn all about it by clicking on the hyperlinked text next to it, currently it is: “Challenge Extended!”
