Another good site for comics and graphic novels is Dime Store Productions.

http://www.dimestoreproductions.com/ (I'm not sure why some of these links are not active on this blog of mine, but just copy and paste to view)

Together with their Picks of the Week, Advertising Space for your comics and graphic novels, Submissions info, Members Forums and Links page and How To pages, its another valuable source for Graphic novelists and those interested in this field.
