I went with Smile to Open Advantage, BIADs snazzy service for open source software to discuss cms’. This of course is for longwill. Plone popped up but was told is hard to learn. This sounds like a challenge to me! I’ve skimmed the site and it looks like this piece of software runs half the web!
It’s all coming down to what they really need. Do they need 3rd party services? Will they have that much content to store? What are they restricted to?
Answers coming soon.
