Make Beliefs is again very simple to use, and requires no registration. At first I couldn't get the "Start" screen on IE, so I switched to Chrome, and there it was.
When you finish you can print the cartoon or email the link, but even after emailing it you can still edit it further (as long as you don't leave the window).

I'm attaching a Jing screen capture, and the link is http://www.makebeliefscomix.com/Comix/?comix_id=21358851C616565
