May I modify the Crash Course to use on my website/on television/at a presentation/etc?

In order to protect the integrity of Chris’ message, we cannot allow others to modify the content of the Crash Course.  We are currently working on a 42-minute version of the Crash Course for use on television and will make it available as soon as possible.  You are welcome to use the existing version as-is.  If you would like to make your specific needs known so that we can consider them as we plan future offerings, please contact us.  Thank you for your understanding.
