Kerbal Klassroom Weekly Challenges

This is the club where people from the Kerbal Klassroom (or other) can come to participate in weekly challenges in Kerbal Space Program. After the weekly challenges died down on the main club, I decided to build a new dedicated club just for challenges/weekly builds. The challenge format will be just the same as in Kerbal Klassroom, I or an admin will pin a post on the challenge Idea page, and the best liked post will be that build challenge for that week.
