Developer Forum in Team Foundation Server

I am exploring the possibility of using TFS portal to add a developer discussion forum, somewhat similar to a typical forum like this:

http://www.javaprogrammingforums.com/java-theory-questions/34993-stack-memory-question-understanding.html

I have used YetAnotherForum (http://yetanotherforum.net/) in the past to set up an internal developer forum and that worked very well. I do not want to use YetAnotherForum if there is something very similar or comparable in TFS. I have used the discussion board in TFS portal with TFS 2010 but it did not appear as powerful as YetAnotherForum to me. Is there something in TFS 2010 or 2012 that can be used instead of YetAnotherForum?
