This question already has an answer here:
Why don't we have Suggest as Answer button near every answer?
I see a lot of unanswered questions (With answer, but not marked) everyday.
It would be great if system can Accept Answer as usefull automatically if there is like 10 suggestions or something.
I am sorry in advance if this is already suggested, but I really think this could be usefull here (I'm talking about all communities in StackExchange).
