How to delete one of my questions ?

You can only delete open question or answers, if they have gone to the vote or resolved they cannot be removed.

The questions and answers stay in yahoo archive available for searching and browsing. only yahoo can delete them if the question/answer is reported.

If the Question/answer is still open scroll down to Pencil Icon and click> select delete question.

Underneath your question is a pencil with the word EDIT next to it. You click on the pencil, and either three or four tabs will pop down, and one will read DELETE QUESTION. You click on that, and it's done. You can only delete questions if they are open. If they are closed and in voting, the only way to delete them is by reporting them. Even then, it's up to the Yahoo! Answers team to decide whether the question is deletion-worthy, or if it violates the guidelines.

You can only delete questions that you asked, and you can only do that while they are still 'open'. Once a question is in 'voting' or has been resolved via a Best Answer being chosen, the question belongs to Y!A and is in their database forever (or until they start archiving old Q&As anyway).

To delete your question while it's still open, go to the question page, pass your mouse over the pencil icon in the toolbar below your question, and click Delete Question.

Only if the question is still 'Open'. Hover mouse over the Edit tab below the question, click on delete. If the question is 'In voting' or 'Resolved', it is too late.
