Where can I find some good FREE Online Comic series?

I just got into Dr. McNinja online & was wondering if there's any other series online that's worth looking into.

Please include links to these sites. Lesser known & obscurer titles are preferred over more common stuff (so avoid X-men, Spiderman, Superman & similar stuff).

Please suggest original works when possible.
