I asked a question on an Stack&nbsp;Exchange site and at the time got an answer which I marked as such ()  Since accepting the answer, a new answer has been submitted which is now more accurate than the original answer (I only noticed as I stumbled across the question in error when going through my account).  Should I be changing my accepted answer or leaving it as it is? Logic says I should update it, but it seems unfair that the original user who answered the question will now lose reputation points (I'm assuming they will anyway once I un-mark their answer) when originally they answered the question correctly.

I had a question of the form "does something like X exist?" Someone wrote a response to say that, No, X does not exist, but I could write it if I liked. I had suspected as much, so I marked his answer as the accepted answer. Today someone actually posted the code to do X for me, and I feel that the new poster deserves the "Accepted Answer" checkmark.  Is it poor form for me to pick a new Accepted answer? Does the original answerer get penalized in terms of reputation?  While the original responder's answer was accepted at the time, I feel this new answer is really more helpful.  Edit: Which of these responses should I accept? What does the notion of a single accepted answer mean with a question that is subjective that could have multiple "right" answers?

I've just answered .  After accepting the answer, the OP then changed his question to another problem - which I know I shouldn't have answered (I should have requested as new question) but I updated my answer anyway.  The OP has now edited his question to remove the essence of either the original or new problem, and instead has a statement saying that the problem has been fixed.  What is the correct thing to do here?  Roll the question back so it's in its original state? Roll it back to the "new problem" state? Leave it and let him continue to get downvoted and/or closed by people who didn't see the original question?

There was  by  (no, another Jon) that had an incorrect accepted answer with 0 votes. I pointed out in the comments that the accepted answer is wrong and started writing my own answer (a workaround, but anyway!). As I finished my answer and pressed Post Your Answer, I realized the question has just been deleted. This kind of bugs me because I really wanted to share my solution. Should I:  repost the question; wait for someone to revert it if possible?  Update I reposted the question (along with my answer) .

Edit: This question isn't a duplicate of . The quote in the highest voted answer on that question is "Bottom line: if you want to get up-votes, WRITE A GREAT ANSWER." that works well in that question. But in this question the situation is that the potentially great answer could just be copied and made to look as if the author of the answer was the one who did the copying. This is not the same situation.  This isn't a huge issue, but it's something I've witnessed more than once now.  Take this question for example:   When I posted  about using jQuery's on change event listener there was one other answer which only said something along the lines of, "you can use AJAX for this", nothing more - not helpful at all, especially as AJAX wouldn't be used for this anyway.  After posting my answer I commented on the other answer saying that AJAX wouldn't be used and a few minutes later  was changed to also use the on change event.  The problem here is that as this edit was done so shortly after the answer was submitted, the original content doesn't appear in that answer's .  Anyone looking at the two answers would think hey, this guy [edited answer] posted the correct solution first so this answer should be accepted.  How would this be dealt with? What's in place to stop people making a really quick invalid answer then editing it as soon as somebody else has posted up a working solution to replicate that?

I have a question about editing practices:  Does it look good to edit a question you have just answered?  For example: say I had just answered a question, then saw that the question had some minor formatting issues. Should I edit it? Does it turn up voters off when they see that I am answering a question I changed, possibly to better suit my answer?

What should I do if a question has changed since I answered it? The other members vote my answer down because it actually doesn't answer the current question.  This kind of editing sometimes happens with  where the OP keeps adding new questions, making my pre-existing answer now incomplete.  But another pattern is when the OP asks an "XY problem" question, an answer points it out, and he changes the question to react to that.  Those answers now not only aren't answers but can look very tangential to people who don't review the edit history.

While reviewing I came upon  by the OP of the question. I believe it was meant to be a comment to another post or comment that I have not been able to identify. Normally I would have flagged this as "Not an answer" and moved on.  But...  For whatever reason, most probably due to not understanding how SO works, the OP marked this post as the accepted answer. I have to admit that this is a first for me - I've never felt the urge to flag an accepted answer before, but I find myself being far more cautious at the sight of that green checkmark.   Should I treat accepted answers like this any differently? Accepting an answer usually (although probably not in this case) means that it is the final word on the issue at hand as far as the OP is concerned, which is why I am reluctant to flag it. What happens to a question if the accepted answer is deleted? E.g. is it placed back into the Unanswered pile? What about the accept-points for its poster?

My question is similar to   I believe this would be useful in the scenario if I upvote a question or answer... and the OP changes it where you no longer think it deserves the up vote you have bestowed upon it.  For example, I upvoted an answer, because I thought it was a great answer... then the OP changes it to add a bunch of stuff that I no longer think makes it a great answer. How am I notified of this change?  I know you can rollback use roll back, but how do you know it was edited without getting a notification!?  I haven't seen any meta asking this question, but if one exists please link it and I will remove this question!    EDIT:   @JoshC brings up a valid point... where not everyone has time to go through all the notifications... but why can their be an option under account preferences to turn this feature on or off?

I have seen this many times, a question is being asked because a previous, duplicate question was asked and answered a few years ago and has no longer relevant answers.  The  is to edit the old question, or add new answers to it, but it is not always happening.  I was wondering, should I still mark it as duplicate and vote to close it? Or just leave it as is?

Let's say I have a problem, and post a question on StackOverflow.  I don't get any good answers, so I end up writing my own buggy implementation, or shelving the feature entirely.  Months later, someone provides an answer.  It looks promising and gets a few upvotes, but by this point it is too late to rip out the old implementation, or I have left the job, etc.  The question is no longer relevant to me.  Do I have a responsibility as the original poster to see if this answer would have solved my problem?  Relatedly, if someone pesters me about my accept rate, is "I no longer have the ability to check if any of these answers are right" an acceptable response?

Answer in question:   I have the answers sorted by votes, but strangely the answer marked as accepted is listed last. The top answer is the one with most votes:    I've never seen that happen before. Is it because the answer was posted by the asker, or is it a bug?

I just answered , then deleted the answer because I realized what I said had already been covered. After deleting, I editing in a note saying why I deleted it, but that edit bumped the question on the home page.  I assume that the question will get bumped if I undelete the answer (which is proper behaviour), but I think in the case where someone edits a deleted answer, there's no point bumping the question for content that most people aren't going to see (and since the answer is deleted, shouldn't be seen anyway).  EDIT: A nifty way to abuse the system (10k+ only!).

An answer on Stack Overflow was recently brought to my attention as possible plagiarism, but I determined that the source of the suspected plagiarism was actually written and posted by the answerer elsewhere and later copied over to Stack Overflow verbatim.  The question  seems to cover the opposite scenario, where someone might want to copy their Stack Exchange answer onto another SE question or elsewhere on the Internet.  Is this an acceptable practice?  I am assuming:   That the answerer has permission to post the answer here, either because they never gave up the rights to the content or they have retained enough rights to also post it here. That the answer is at least minimum quality and makes an effort to answer the question (that is, it's not simply a rant from the answerer's blog, or random ponderings with nothing to do with the question asked).   In response to Anne Daunted's question, no, they did not disclose that they were copying over content that they had previously written and posted elsewhere. It got brought to chat as a possible plagiarism to be flagged. I investigated and declined to flag, commenting instead that it looked ok enough to not be flagged for summary deletion by a moderator. Instead, I decided it would be best to leave it to voters to decide how useful it is.  While this question is inspired by something that happened on Stack Overflow, it belongs here because it is relevant to every site, and there is no obvious reason that such a policy is or should be different across the network.

I have posted questions on SO for which I have received answers that do not answer the question. No correct answers were offered (I guess I have really good questions ;) )  People tell me my accept rate is low, making my questions less attractive for answering.  Should I accept the wrong ones to boost my accept rate? Is there another option? Can I mark an answer as wrong?

I asked a question that has been marked as a duplicate. I read a lot of similar questions and explanations in advance but I couldn't find a solution. In the question that should answer my question the asker used a different (not working) approach. There is even an answer that would work for my case however I'd rather consider it as a workaround than a solution since I have seen examples using my approach.  So I would like your opinion in that case. Would it be ok to repost my question while explaining why other answers didn't help me? I edited my question but I think it's not getting any attention anymore. Naturally I will remove the old question.

Twice today I noticed that my reputation increases with 15 on Stack Overflow, but when I click to see my account, the change is being reverted and none of my recent answers are marked as accepted. Then why does the reputation on the top of the page change ?

I asked a  on stackoverflow at the end of last year for a beta or pre-release product and got the answer I wanted.  3 months later someone else answered the question with the correct answer for a newer release.  This answer got way more upvotes than the one I accepted.  I only noticed this today so changed the accepted answer.  Can I get a notification email when an answer gets say 10 more votes than the one I accepted.  Just to let me know something might be up.
