Thank you for your work.
I still think "known problems" is really bad and thought your "common solutions" idea was better.
However, I definitively see Mrak's point about "people know what their problem is" , but when I see "known problems" it don't want to click on it, since I know my problem, but Im here to find a solution. I think the initial "Common Solutions" idea was better and adding Mrak suggested structure under this heading would also be great.
Maybe this is only my point of view, so if more people think the problem => solution structure is better, it is fine I guess.
