How do I delete Old Questions?

How do I contact Yahoo to delete questions from my old account, password forgotten?

• I forgot my old password, have set up a new account How do I delete all questions sent from my old account, it was a year ago, they're still on there?

• Answer:

  Only open questions may be deleted. Once they are in voting or resolved, they become the property of Yahoo and go to their archives. They even stay there if you get another account or quit YA entirely. To delete an open question go to your profile, go to "my questions". Click on the question you wish to delete, underneath it click "+", then click "delete question".
