As it's Saturday and i'm a bit of a functional alcoholic, i've made a blog which will be a collaborative base for me and some of my classmates at uni. From there we'll share designs which we believe have marketability, and present them as such (show prints as printed, badge designs made up into badges, etc).
This can all be found here: http://illustrationafterhours.blogspot.com/
As to who the contributors are, i'm not quite sure yet... heheh...
Also, in the pipeline at the moment is the idea for a mass collaboration of illustrators into one big, self published, book. So, watch this space I guess!
