[Zope] Query on CMF.

Hi, I am using Zope 2.5.1 and am using CMF site to manage the pages. With the current workflow, pages under a particular user can be viewed by all only if it's state is published. This is fine. But if the user wants to make some changes he will have to retract the item for doing so. During this time no one is able to view the page. Is it possible to make the latest version of the page available for viewing by other users? Also the edited new page should be made available after it is published. Any workflow available to implement the same? Expecting an earlier response. Thank you. Regards, Paul.
