I'm looking for a reliable / flexible FREE CMS to run on an intranet. I'm willing to invest in the time to learn the system. I'd be interested to see what the opinions are on Postnuke vs. Plone (Zope).
I have to run it on Microsoft IIS 5.0, so if it's only for apache, linux, sorry.
If there is another popular/recommended CMS, I'd be glad to hear it.
Here are Some criteria: SUPPORT, Quick Searches, Forums, Polling, News, Document Storage ie. policies & procedures, Flow process for approvals.
