Is anyone aware of a Question and Answer webpart for sharepoint 2010+
I'm looking for similar functionality to the Stack Network rather than a forum.
The audience for this site will consist of scientists asking questions of other scientists across disciplines. They will be seeking authoritative answers to their questions and building a knowledge base for the future.
For security reasons we're unable to take advantage of any API's.
We've looked at NewsGator Social Sites, but it's too social for our needs and Forum products like Social Squared won't generate authoritative enough answers to build a knowledge base.
