Q&A Board: Nested comments to clarify questions and comment on answers
Our goal is to build a community around a Question & Answer board. We've been looking at the few open source Q&A solutions available, such as osqa, askbot and question2answer, but they aren't suitable for various reasons. We believe that vanilla forum is the best choice. Now however we are facing one major issue, vanilla forum does not natively support a nested comment structure (1 additional level, similar to the stackexchange sites would suffice). For a Q&A Forum of the size we have in mind it is crucial to be able to sort the answers with respect to the number of votes received, which does not make sense without the ability to clarify questions and comment on specific answers.
So our question is, whether it is feasible to implement a comment on questions/answers solution.
