How do I do a "reply to all" when replying to an e-mail?

Possible list date/time when replying to email in Yahoo?

• When I reply to an email in my Yahoo account, it will print the name of the person and their email address, followed by the body of the email, however it never stamps the date/time the email was originally sent when responding or forwarding it. Is there a way to include it? I couldn't find it in the Options menu...

• Answer:

  if you forward the message back, instead of using reply, the date would be in the body of the message. another option would be to copy the date before pressing the reply button, then pasting the date into the resulting box. there doesn't appear to be an option to get the date automatically.
