Please add a Solved Discussions menu option in the Community (screen shot below). This would be a great reference tool in addition to the Help Articles.
I like this idea, however it would require more people actually marking their question as solved. This is a feature we strongly encourage to help other users find what they're looking for faster, but still we don't have complete buy in.
And something to think about is how to best navigate or sort in this tab, i.e. by topic, votes, comment votes etc? As I belive the content could become overwhelming quickly and it would defeat the purpose of making discussions more granular if it is not user friendly. Definitley something to think about!
