How do I add signature for my outgoing yahoo mails?

• my friend's mail 2 me always have this message at the bottom of the message page, how do i do that

• Answer:

  To create your signature: Click the "Mail Options" link in the upper-right part of the page under the "Sign Out" link. On the Mail Options page, click the "Signature" link in the left Personalization column. Type your signature in the text box and click the "Save" button. Include whatever you like, but remember, it will be appended to your outgoing messages. An example of a signature: Joe Smith Manager XYZ Corporation (123) 456-7890 "You break it, we fix it." Have your signature attached to every message you send by checking the box next to "Add signature to all outgoing messages" below the signature field. Your other option is to include your signature with only those messages you choose by selecting "Add Signature" on your Compose screen.
