First poster can pick "best reply" and more.

Is there some way, that if someone creates a new post Asking for different answers to a question that he posts. Then different users answer when they reply to the threads. I am looking for an option where the original poster can choose the person that has the right answer.

eg:
New Thread:
Can some one tell me what 2+2 is? I will accept the first two correct answers.
-----------------------------------------------
Post reply:

Yes, that answer is 4. [Button] <-------Choose this person (thread)
------------------------------------------------
Post reply:

Yes, that answer is 5. [Button] <------The option is there to "choose", but they
------------------------------------------------ got the question wrong.
Post reply:

Yes, that answer is 4. [Button] <------------Choose this person (thread)
------------------------------------------------

After a certain number of people are chosen, I would like to have the ability to close this thread, if say, I am looking for eg; 2 correct answers. So after I click two correct posts, the thead automatically closes. I would like to make this forum specific as well, where as this isnt available in all forums just ones that are specific to the Ask questions forum.

I have more questions and am looking for someone to help me with this. Thanks, DAG.
