Your options as the asker of the question are laid out in this Help Center article:
Decide if the answer is helpful, and then...
Vote on it (if you have earned the appropriate voting privilege). Vote up answers that are helpful and well-researched, and vote down answers that are not. Other users will also vote on answers to your question.
Accept it. As the asker, you have a special privilege: you may accept the answer that you believe is the best solution to your problem.
If the answer is exceptionally good, and you have earned the set bounties privilege (75 rep required), you may also set a bounty.
As for badges, they are awarded by the system, not by users or moderators.
