Allow users to mark “accepted” answer on someone else's question?
Scenario is just now I googled/found this and it seems to me, given the number of upvotes on the question and the one and only answer, that it should be marked. It's not that I care about the authors points, but more that I like to see the quality of SO as wiki/kb resource to programmers like me who get alot of use from it be as high as possible so it is successful as possible and thus stays around.
--> this is clearly not a big thing, but seeing the green checkbox when I arrive at a SO question makes the experience better for me. I think it makes me feel that someone who knows more about the topic at hand than I do has "signed off" of the answer being valid.
