Hi Akshat,

In order to contribute content to Khan Academy  you must have a partnership you can email your inquiries to partnerships@khanacademy.org.

Should you have any further questions I will be happy to help.

Akshat---  I just wrote up a loose outline for a module in chemistry on new arrangements of the periodic table, integrated a few example illustrations, and posted it in this forum. If you are just looking to inspire new content, this seems a great way to solicit community feedback. Maybe the "partnership" that Katrina wrote about applies to finished content and not exploratory content.
