Can we have useful post button ?

Can we have a useful post button in the threads. The facility is there in many reputed forums. They call it the best answer button.

I have to admit it's useful, but when only one guy answers (and maybe really badly) doesn't he get the "Best Answer" reward?

I am getting daily from Yahoo Answers regularly
even after 2 or 3 years !

I reinstalled the windows folder. now i get a message i cant access my old my documents folder? - Yahoo! Answers

Only if someone clicks the best answer button.

it will be very useful to have a useful post button as "best answer".

but there should also be a "no best answer" button.
