Is it possible to permanently delete a Yahoo Messenger account?
It is possible to delete a yahoo account but it will also delete everything else, including your yahoo mail and any other yahoo areas that you use that ID for. Once you delete it you
won't be able to reactivate it. Yahoo help also says that terminating your Yahoo! account does not alter or delete your Yahoo! People Search listing, which you need to edit or delete yourself. Here is the link to the page with all the info and links for deleting the account.
