I just happened to visit the website of the STEM Challange (http://www.stemchallenge.org/) and saw the game making resources page. I was surprised that there was no mention of C2 there (not even an image).
I think that it can be a good promotion for Scirra if they register/submit their softwate to student challanges like this. Just like they are on the engine list here: http://www.g4cstudentchallenge.org/students
