If I enroll to see the reports, etc., is there printable content available, or is it all in video form?

The Martenson Reports and Newsletters that are available with a
enrollment are all in print form.  Podcasts are only available in
audio format.  Crash Course transcripts are available on the Crash
Course chapter pages under each video box.  There is currently no
information exclusively for subscribers that comes in video form,
although there are plans for future chapters of the Crash Course that
may be available only for subscribers.
