Hello. My name is João Alves and I am a participant on the Google Highly Open Participation Contest.
One of my entries consists of a SilverStripe theme called Olive Sunset, a versatile dark green theme that includes support to the blog, forum and e-commerce modules.
Please see it in action on the online demo and download it if you like it. :)
Also, if you have any comments or if you find any bugs, please contact me. I would be very glad to hear from you.
