How does the bounty system work?
I asked a question and it received a couple of answers. I'm getting a message that says I may want to ask for a bounty on the question.
I'm not really sure what a bounty is or does. However, I did answer my own question — in case anyone else needed the answer for something similar — and I am not allowed to vote for my own answer. What is proper Stack Overflow etiquette in this situation?
