Hi folks,
I apologize fro relying on your charity for htis question -- I ought to figure this out myself, but am so slow that I've run out of time.
I dhave a number of lecture slides writen in org-mode. Normally I simply export to reveal.js using org-reveal. However, I now have to share these notes with a co-instructor who uses markdown, but not org. This is not fatal; I can export to markdown mode and use pandoc to create the reveal.js slideshows.
