If you have a Yahoo! account, you can submit any question to Yahoo! Answers and receive answers from other users, and you can respond to their queries. If you want to delete your own question, you can do so easily as long as you haven't already chosen a "Best Answer." Once a question is resolved, you can no longer edit or remove the question.
Log in to Yahoo! Answers.
Hover over the "My Activity" tab, then select "My Q&A" from the drop-down menu.
Click the "My Questions" tab, then click a question to open it.
Hover over the "Edit" button, then select "Delete Question" from the drop-down menu.
Click "OK" to confirm.
