Thanks for checking out the app. A couple weeks ago the free heroku database got filled up. I am financially challenged right now otherwise I would pay for an upgrade. The cool part is that exams a fairly simple, if not a pain, to type out as a JSON file.
I did just delete some junk that was on there so you may be able to create an account now.
