I have a small issue to be answered. What are the boundaries and scope for copyrights at Math.SE ? . To explain further, suppose I have described a new idea in the question, what if someone copies and use the idea ?.
Similar situation, suppose if I present some new way of solving a problem and posted the answer, and others have used it. What is the situation then ? .
I am not after recognition and fame, but there will be some body who feel bad doing so. So I asked this question for general purpose. Please do clarify my doubts.
