Update redmine.org theme
The redmine.org theme is pretty old-fashioned looking and doesn't help sell the product.
When I try to push the use of Redmine in a business case, the first thing everyone does is googles the website and browses to it.
I asked a random sample of 20 people around of office what they thought of the design of redmine.org, all of them provided negative feedback many siting that the page looks old fashioned.
I believe updating the redmine.org theme to something more modern and visually appealing would go a long way to the further widespread adoption of Redmine.
