Website Updated May 15
Ok, the call for cities is closed. I redesigned the whole webpage. I think I managed to make it more beautiful, more clear, give it a better structure and menu. And the "Global Challenges" and the "Mentorship Program" is added.
I had to erase the stories from 2015 from the main page. They made the page too heavy. I integrated them into the documentation of 2015 and placed a prominent link to the documentation on the main page.
Feedback and suggestions as always welcome.
