Just so you are aware, at marker 3:36 "Due Date" is referenced. Then at 3:47, it disappears and reappears.

Thanks for pointing that out. It's just a video goof. I recorded my lessons in short segments. If I mess up, I stop recording, delete the video segment file, and then start over. Looks like I forgot to delete that segment, reset (got rid of that field), and then started over. Not the first time I've done that. One time I said something wrong, said "oh shit" in the video, and didn't catch it. That video has since been edited. :)
