As technology evolves, answers to some questions might get outdated. Now, if I see a question which I know has outdated answers, I can either post a new answer, or ask a question which points out why all the old answers are no longer valid and ask for newer answers.
But what if I don't know whether or not the answers to a 10 year old question are still valid and relevant? Am I allowed to post a new question asking if those answers are still correct? Or is there some other way of doing this?
Note: simply commenting on the answers will not work, since the OP is often no longer active on the site.
