Dear John,

Thank you to every person who supported MIT OpenCourseWare during this year's MIT 24-Hour Challenge! Whether you donated, spread the word, or shared your OCW story, you and your efforts make it possible for us to keep meeting learners and educators where they are with the latest educational resources from MIT. We're grateful to you!

Sincerely,

MIT OpenCourseWare

P.S. If you have a moment, would you consider sharing your OCW experience? We'd appreciate your feedback.
