I found an old thread from this list (from May 01) stating that you need to add a python module in order to modify workflows, but the CMF promotional movie (http://www.zope.com/Demos/cm3) shows a ZMI screen for doing this. I've gotten to the point where I can add a new workflow through the ZMI, but I can't assign it a workflow type other than "Simple Review / Publish Policy". What's the right way to do this?
