Sometimes a user offers an Answer which can be proven false, but the proof doesn't fit in the comment box. Is there a best practice for pointing this out? (I'm explicitly not asking about differences of opinion or judgement, but things that are provably true or false in a mathematical sense.)
- Offering the proof in a different Answer to the same Question doesn't seem like appropriate use of the Answer feature.
- Breaking the proof into several comments is tedious and hard because the edit duration expires.
- Asking and Answering a new Question, and then posting a comment that links to the new post seems like the best option.
Have I missed a better alternative?
