We haven't had time to do any of the vexrobotics.com challenges. We've been busy building Vex bots for WPI's Savage Soccer, the FVC Challenge, and our own experiments building 1/3 scale FRC bots out of Vex kits.
I think more people would try these challenges, if there was a way for them to meet and run the challenges and compare notes. A non-competitive tournament / showcase that would also build more interest in Vex.
People like to be able to show off what they've accomplished.
