A user posted a question that I found very interesting. I posted an answer to his question, but as it was a question about logic there are other possible answers. I would be interested in seeing other people's responses, hopefully better than mine.
However, I realize it might seem strange or even a conflict to add a bounty to a question that I have tried to answer myself. So I'm wondering:
1) Is it possible to add a bounty to a question even though I posted an answer? I don't know yet because the time limit hasn't elapsed.
2) Is there any hard rule against it, or any reason not to? I want to see more opinions on the question.
3) Supposing the poster accepts an answer before the bounty time limit elapses, is there a way to add a bounty or otherwise bring attention to the question?
