[Zope] Creating and Updating ZClass instances

I'm trying to set up a simple trouble-ticket type application using Zope. I defined a ZClass for the individual tickets and added a few instances through the management screens. That all worked fine. But here's the catch -- I want the users to be able to create and update tickets through the regular web site rather than through the management screens and I can't figure out how to do that. Is it possible? I keep having the feeling that what I'm trying to do is really simple but I just can't quite grasp it yet. -- Web Mayfield EDS Medicare Business Services 972-604-2277 (8-834)
