Say I've proven a theorem or found a solution to a problem. I'm close to being sure that my proof or solution is fine. However, I'm not entirely confident in my jugdement. Maybe I'm new to the topic, or I remember that I've thought correct my incorrect proofs of the same difficulty level many times before. Is it considered a good idea to post the proof/solution here with just one question: "Is this correct?"
This seems to be an accepted practice, as many others have done it, and I can't recall reading any objections.
Personally, I have a small objection, namely, if your proof is correct, there's not much anyone can do except answer "Yes" (with enough non-printing characters to make the answer long enough to be posted). Let me propose an alternative course of action, and see what people think:
Post the theorem/problem as a question, and your proof/solution as an answer, indicating in the question that you are going to do this, and that if no one shoots down your answer in the next few days then you are going to accept it.
