I click on "Get Started" on this page (http://html.adobe.com/edge/inspect/) and I'm prompted to log in. Once I submit my user info, there is an overlay with the terms and conditions. I can't find where to agree to the terms and conditions, the only thing I can do is close the overlay. Then I'm back at the login page.
Edit: Never mind. I launched my browser in incognito mode, then clicked on the Sign In button at the top right of the apps page (https://creative.adobe.com/apps). That seemed to work.
