Support Us

This project is Open Source, but it does take time and resources. Especially as our popularity has grown we have server costs. We were also able to make great progress during the Summer of 2013 thanks to a generous grant from ACM-SIGCSE that supported one of our undergraduate students. It would be great if we could have a student working on this all the time.
