As Graffiti CMS is being rewritten as I write this at codeplex as an open source project to bring it to Graffiti CMS 2.0, some of the themes created for Graffiti are old and the newest ones cannot be found. If you go to http://extendgraffiti.com/ you may find some of the themes, yet not a way to download them. I have kept a few themes that include avatar images per user as well as RSS and ATOM feed icons. This 3 below include everything you may want in a blog. As you can see, I changed my blog to go back to the Skittish Theme that I learn to love. Please feel free to download any of this themes and let me know if you make any good modifications on those.
