See Deme
You may try out the demo of our release 0.7.0 (Skeletal) of Deme, and make comments, post tickets, etc., on our Trac site. You may also browse the documentation for the software. Finally, if you are so inclined, you may download the source code from our Trac site.
Please bear in mind that this is an architectural release of Deme, with limited functionality. Check back often, as new features will be added regularly as they are developed.
