How do you change a wrong answer on Answers?

Answer 1

Answers is a wiki, which means that it's a website collaboratively written and edited by the users. And so, we invite you to contribute to this answer and make it better! To do so, simply click in the box where it says "Improve this answer", and add your contribution. When it's complete, click on "Update Answer."

New and somewhat new users sometimes are not able to edit answers that do not appear to be bad answers. You can modify your ability to edit answers by contributing several good answers to questions and build up your Answers.com "reputation." If you answer and ask questions for the next two weeks and still cannot edit an answer, please let us know. If you would like a question edited immediately, you may send us the edit and we will make those changes!

Answer 2

Usually this cannot be done. Due to the potential for vandalism, an account is required to be able to edit questions and answers. Nowadays, getting an account is painless, and you don't need Facebook. As long as you are at least 13 and have a valid email address, you can sign up.
