I asked a question a while back about quasi-liches and got a few responses and even selected a suitable answer. But now I have found a newly published answer to the question.

How should I go about adding an answer to my own question? What happens to the originally selected 'correct' answer and it's poster's reputation? The answer would be of interest to anyone reading the question but the original also answers it very nicely.

No question is too old to answer, and there's no stigma against giving a good answer even if it's to your own question!

As counter-intuitive as it may seem, the Stack Exchange isn't really about giving answers to the people who ask questions; its primary goal is to collect good answers to the future users who have the same question.

This means questions never get "too old" to revisit, and it means that if the asker is the one who finally found a good answer that's just as awesome as if anyone else found it. We even encourage people to self-answer questions they hadn't asked yet!

Now, some details:

If the existing answer is mostly the same as the one you'd make, but you have more details that'd be useful to add, you might consider leaving a comment or editing the original rather than adding your own new answer.

If you use the "Answer Your Question" button at the bottom of your own question's page, the answer will get added to the list like all the others. You can choose to remove the "accepted" checkmark from the previous answer and give it to your own if you think that's accurate--but you don't have to, it's totally your call.

If you move the checkmark to your own answer, the original answerer will lose the 15 rep from having an answer accepted--but you won't get 15 rep because it's your own post you're accepting and that'd just be weird. The original answerer will not lose any vote-based reputation, and you'll get vote-based rep on your own answer as usual.

    \$\begingroup\$ It may be worth pointing out the one other difference between own-accepted answers and other-accepted answers: when you accept your own answer, it is sorted based on its score (as if nothing was accepted), not first the way answers are when accepted by someone else. \$\endgroup\$

    \$\begingroup\$ @KRyan yeah, that's one that often makes me do a double-take, still. Good catch/call. \$\endgroup\$
