I'm testing Q&A, which I find to be very interesting. I noticed that any answer to the question thread marks it as "Answered".
This can often be false. For instance, If I ask "what is the color of a crow?" and someone answers "I don't understand your question", the question will appeared and "answered", which is not the proper status.
Only the original poster should be able to mark his/her own question as "answered" or if an answer was voted enough, then the question should be considered "answered".
What do you think? As it stands, having partial answers marked as "Answered" is semantically correct, but can be misleading for users who would interpret that as "solved".
