What is the best way to preceed if we notice an answer that is not correct anymore for instance after a protocol update?
The three options I see are:
- Adding a comment to the answer to notify the author: fair to him but assume he is still participating and willing to update the text.
- Editing the answer: I think it requires an approbation by the initial author (who may never come again) and the reward for the new author is small.
- Adding a new answer: it gives more reward to the new author, it may become the accepted answer (helpful for futur readers).
I seems to me that the polite way would be to let a comment and then to add a new answer after some time without response.
