Artipolis is an art network to which I was recently given an invitation. It offers messaging, connecting with other artists and forums (the best traditional art forums at the moment are over at Rational Painting however).
They offer a free ‘Pro’ site where the artists can put up a very elegant website with very little effort. At the moment I’m using it for all of my available work rather than continually updating my own site. I’ll probably move the whole site over when I figure out how to keep my blog attached. In the meantime you can see the archive of all of this years work under the ‘gallery’ tab.
