The site is exclusively for artists and art centered websites including webcomics, portfolios, video and animation, art blogs, music, etc. They've been working on it for a few months and finally got everything up and running.
Although things are still being worked out, they'd love to have anyone register and try it out. Hopefully this will be a great way for artists to promote their artwork and perhaps learn about other artists and webcomics as well.
