How does the bounty system work?
I asked a question, offered a bounty, and wound up finding the answer myself and posting it. If I accept my answer, what happens with the bounty?
You can give the bounty to any (other) answer to your question. If your answer is the first fully correct solution to your issue, but other answers made progress towards it or contributed to you solving the problem, award the bounty to one of those answers. Otherwise, just let it expire.
