How do I find the question that I gave a best answer on?

You may have misasked this.

For a question you GAVE the Best Answer, you go to the MY ACTIVITY tab at the top and look through your list of questions. If it says resolved, either you gave the Best Answer or voters gave it. You just have to look at the list till you find the question you want.

For a question, you GOT a Best Answer, you will get an email or you again go to the MY ACTIVITY tab, the My Answers tab, and click on the Best Answers link. All of the BAs you received are listed there.

You should have received notification e-mails that your answers were picked as Best Answers. Check your Yahoo Mail inbox by going to http://mail.yahoo.com/ - when you open them, you'll be able to see the questions for which your answers were picked as the best.

Also, you can go to your Q&A profile by clicking the My Activity tab at the top of this page. Scroll down to the area where you see four tabs; the My Answers one is automatically selected. Right under the tab, click "Best Answers" next to "Filter by". All your best answers will then be listed there. Click the questions individually to see them.
