How do we contribute content for a new course?

We are a non-profit research center and have been working with an outside donor to create a free-content course on American Government and would like to submit it to the Kahn Academy in hopes the content would be used by teachers, students and home school parents.  The content was created by a team of PhDs and graduate students and has already been ported to a free website for online use, PDFs, Canvas and Moodle.

Is there an interest in reviewing the materials and making them available (for free) on your site?  What is the process?

Thank you
