I found a great little website called Carbonmade: Your online portfolio.
It's a great way to get your art put online really fast and for free without advertisements. I like the layout, and it allows enough space for me to keep my work for now.
Some other great services are similar to myspace such as:
-a great place to get to know other student artists and make fun connections through art.
-set up by the highly respectable Saatchi Gallery. Nels is a part of this, and I think more should join him from LaCrosse.
I'm sure there are others too.
