Here's what I get when I go to the StoryMaps in the MOOC:
Hmm... there seems to be an issue
There was a problem accessing this story or this page. Please try again or contact your ArcGIS administrator.
I am the administrator for my account - have no idea why it's doing this and I don't see anyone else complaining about this problem.
Not sure if it has something to do with "negative credits" on my ESRI account which I don't know how I ever got and have asked to have that fixed. I thought they took care of that. I don't think you need credits on your account to read "StoryMaps" though. But maybe I'm wrong. I have too much on my plate to try to figure this out - so I guess this MOOC isn't going to work for me.
