Hi team,

Since the material has been pushed to master, this pull request is a little unusual. Please add any comments to the docs here by the end of the day Monday, September 29, 2014. I will make changes and create a new branch and a new PR for the changes. Then, I will discard this PR. 

Please ping me if this doesn't work for you.

Thanks,
Evan
Agreed, in the list of use cases above, you separated out "Primary Authentication" from "Authentication with an Unenrolled MFA Factor". This is now showing authentication with an unenrolled factor, when it should just show the "SUCCESS" state and no factors.
