how do i delete old questions asked on my profile that are no longer needed?

You can only delete a question if it is still OPEN and it is your question. To do that, go back to the question (click your avatar, name, or "My Q&A", click "My Questions, click the question), use the pencil under the question to access the drop-down editing menu, and click delete. If you do this, the question will be deleted from the database and the public view of your profile, but it will still show on your view of your profile, just greyed back so you can see it is not active.

Questions IN VOTING or RESOLVED are the property of Yahoo! Answers, since this is a public database, and cannot be deleted, except for violations, and then Y!A gets to make the decision, not you.

BTW, it does not clog up YOUR computer memory -- this information is all saved at YAHOO, not on your computer.

Hope this helps!

If the question is "open" for answering you can delete it by going to the pencil sign below your question and clicking "Delete question"..

If the question is "In voting" or "Resolved" you cannot delete it.. It stays in your profile for ever, and ever, and ever, till the end of the world...=)

Resolved questions can't be deleted, and they shouldn't affect your computer.
