I just wrote an answer that, on reflection, was misleading/wrong. I know the OP had seen the answer because they commented asking for further details. I then added a comment apologising and explaining that the OP should wait for another user to answer and then deleted my answer.
Will the OP get to see my comment now that I have deleted the answer?
If not, what is the etiquette for retracting answers which you later realise are incorrect?
I feel I should delete the answer as soon as possible, not least to hide my embarrassment, but because I suspect seeing that the question has an answer reduces the probability of someone else reading the question and providing an answer.
Edit: I think I just answered my own question. I should have left the comment on the question rather than the answer.
I'll leave this open in case anyone has other ideas. And I can't bear deleting two posts in one day :(
