moves to Plone has been running for quite some time on a commercial product called zExtranet.

We've now moved to Plone and are much happier, however the experience wasn't without it's ups and downs. There does appear to be a little incoherency between providers of all the (very fun) components that can be added. For anyone else out there who wants all the toys, I strongly recommend going directly to the latest CVS and ignore all the existing pre-existing tarballs that can be found on the Zope sites.

Many thanks to the Plone Team!

Oh, not to forget the plug - come see what an amateur can do with Plone at
