Hello John, 

The OpenCourseWare community’s response to the MIT 24-Hour Challenge has been awe-inspiring! We’re about halfway through the day and we’re only 150 people away from reaching our goal!

If you haven’t yet and are able, will you please donate to OCW by 11:59 p.m. ET tonight?

A gift in any amount today means so much to us—and the millions of people, including you, and learners like Mary, who turn to OCW every day.

Thank you!

MIT OpenCourseWare Team

P.S. If your gift and this message have crossed paths, please accept our thanks—we’re amazed by the generosity of our global OpenCourseWare community!
