Can you actually log in and do anything? I created accounts last week, and now can't log in with them, or can log in and get a blank white screen.
I've just tried creating yet another count. It's hung up on 'step 3' ('please wait' - modal spinner, assuming it's emailing my email address). 3 minutes spinning so far.
OK - it just got done. Got an email. Clicked the link. Logged in. Pause... Taken to https://www.healthcare.gov/marketplace/auth/userprofile which is just a white screen.
So... still not working for at least some people.
