Description
Right now, there is a "duplicate" close reason, but it doesn't link to the proposed duplicate. There should be a system which does this, suggesting the duplicate in a box below the question and allowing the community to vote on that. When a threshold is reached, the question should be closed as duplicate with a clear link at the top of the page.
This is essential to building a store of knowledge, rather than just a forum.
It can also enable reports like "most duplicated questions" — which is to say, actual FAQs.
