I'm confused -- is this the ZMI's "Add..." dropdown?  Or the
list of content types in 'folder_factories'?  Normally, members
won't be able to see the ZMI, nor should they need to.

I looked for a CascadingFolder product on Zope.org, and didn't
see it -- can you give a URL?  Also, is this a filesystem-based
product, or a TTW one?  Your last step seems to imply a that
CascadingFolder is a ZClass, but the second step seems to say
that it is a filesystem product.

To diagnose, try getting to the ZMI of your CMFSite, as manager,
and edit the URL to show:

   .../CMFSite/manage_addProduct/Cascadingfolder/addCascadingFolder?id=foo

If that works, try again as a non-privileged member, using the
path to the member's "home" folder as the base.  If that works,
then the CMF is at fault;  please let us know.  If not, then you
need to configure your CMFSite to allow the "Owner" role the "Add
CascadingFolders" permission.
