This blog was created for advanced painting students at Humboldt State University. It acts as an online forum for them to share finished works, discuss ideas and influences with one another and a broader audience, in hopes that it will foster use of the internet as a means to research and develop their artistic practice.

you guys should check this out too. I havent been there in a while but a couple years ago it was free and still might be. They would make prints of your work and give you something like 20% of each one that sells. Its supposed to be cool but I never got too involved.
