Just saw this
website, and thought it might be good to share ^_^
It's features are pretty simple - you can create a portfolio hosted with them, with a choice of black/white theme and serif/sans text. Then you create 'projects' and can upload images within them, and write a bit about yourself, and get plugged for a short time on the main site. You can see mine
here, although its not very polished and my thumbnails aren't well done at the moment. But you get the idea ^_^
It's not so much the function that's interesting about this site, but the design. It's very Web 2.0, which I'm sure will go out of fashion soonish, but looks pretty cool now and does make for a nice, easy to use interface.
If you make a CarbonCopy portfolio, post it here for visiting!
