I was recently invited to join the facebook group :Indie Comic Source

Its a place where indie creators and self-publishers can share their work. And share they do. It's amazing to see all the comics people are creating on their own and the quality is high. Definitely worth joining if you want to see how people are creating comics and what they are producing. And of course, its a great place to let people know about your own projects.

From the page:
"Welcome to Indie Comic Source, where any independent artist, writer or company can share and promote their work! Please spread the word to anyone looking for a place to share their stuff."
