A CMS created by one of the developers in The Working Group, the company that I work for. Will be happy to pass along any questions or comments you guys may have, and hopefully have him answer some questions himself too!
Are you using it production? Is this something TWG is using internally as work flow?
I notice that a number of tags are available but I'm still unsure of their usage. The sample pages included were somewhat light so if you have better samples that would be helpful.
Apologies on the late response, didn't realize we got a comment here.
Thanks for the questions! We're using CMS for many of our clients and our product (PostageApp.com)
Are you looking for further clarifications on tags and sample code? I believe Oleg (@GroceryBagHead), who created the CMS, is working on a full wiki, so you might want to stay tuned for that. :)
