Why do you need to communicate with me before I even get a chance to demo the app?

For communication at anytime in general, not necessarily before using the app. If you're uncomfortable with us keeping a record of your email at any point in the future and would like us to delete your account, please feel free to drop [email protected] an email from the same email that was linked to your GitHub account at the time of signing in to the CS50 IDE and we'll be more than happy to help you!
