@mehdikazi You should be able to pull this new information from the site. We need to update just the about TEDxBerkeley section (essentially just the theme for now), although we'll likely put in some new copy. Take some time to play around with the styling as well so you have an understanding of how the XML layout stuff works, and shoot me a message if you have any questions.
