What's happening with the site?
I see that you've changed your design. Why can I no longer review as I used to to achieve mastery of a section and why is the vocal not working. A little hard to type in Spanish something I can neither see nor hear.
Look at the discussion on their blog about today's changes. But check your settings to see if your mic or speaker is turned off. http://blog.duolingo.com/post/32680712136/a-new-skill-page
