[Zope] problem with zope version mgmt

I am using 2.1.4. After saving my changes to a version I cannot see them until I got to the control panel as superuser and use version management to save the version. But the problem I see is that the superuser has to manage this rather than the individual developers themselves ?. What is the difference between saving individual versions and saving from the control panel ?. sathya -- ########################## necessity is the mother of invention ##########################
