Hello,
The Appathon is realy great, where students/participants learn team work and they have to have, time construnts and Themes into considration while submitting there work.
As we do have badges for different categories, including App of the Month, it would be realy gereat to include a Badge for Appethon, what badge name should be for this category, our community is realy great to help in suggesting the name 
What I have seen here is badge is also a driving factor for the learnears to be motivated, yes ofcourse, this is not the only one, there are many othere factors to for them to invent and keep learning and creating apps using MIT App Inventor.
Please share thoughts on. Thanks
