Accepting answer without upvoting?
I see a lot of posts where an answer has been selected as the best (green tick) but not upvoted by the OP. How about a feature that upvotes the answer when you click on it as the best (accepted) answer.
The upvote text says (this answer is useful) it is most likely that it is useful if it is the best answer, and you could always have the option to undo.
The caveat I guess would be if you answered your own question as you wouldn't want people generating points for free!
