Let me know if you have any questions. I want to thank Krzysztof Lower and Brandon Ridge for all the great work designing and implementing the version you see on the website. Thanks also to Brian, Jason, Kristin, and Jenn for their invaluable feedback. Special thanks to all the students who helped us test our prototypes, answered surveys and interview questions, and were patient while we got this version out. We hope it’s an improvement, but we’ll just keep making it better. And thanks to you, for reading.
