How do I add a signature to my outgoing emails from Yahoo mail?

How do I add my "Signature" to some emails and not others?

• How do I add my "Signature" to some emails and not others? There used to be a little box at the bottom of my yahoo mail compose page to check or not check when I wanted to add it. Now it's just gone.

• Answer:

  Yahoo has made some changes----and that's one of them. You no longer have the option to check the box---to either include or not to include. Your signature is ALWAYS added on the TOP of the composing page---whether you want it or not. IF you don't want it on certain emails----you will have to erase it like you would any other text. This link shows a list of some of the changes----the signature change is about the 5th one down. http://help.yahoo.com/l/us/yahoo/mail/classic/basics/whatsnew-01.html
