The code that you're using is basically designed for adding ZClass instances
automatically via DTML. For example, in KM|net News, when someone submits an
article, the AddArticle method will take their form input and create a new
ZClass instance. It automatically sets the ID of the new instances to a unix
timestamp. AddArticle has a proxy role of "Manager" so that it can create
the instance.

If you have Manager permissions, you can do this via the management
interface. (Just select your ZClass from the Add pulldown menu.) Or you can
always create your own custom form and then add the ZClass instance based on
that form. This is what I do in KM|net News. incoming.html is the form,
AddArticle is the method which processes the form.
