How to forward an e-mail to my entire contacts list with the new yahoo mail service:

If you have a large contact list, it's going to be time consuming. (Even if you make lists for your contacts, there is no way to select all that I can find)

First click on "Forward conversation" (arrow pointing right shown)

next click on "To" and it will say "add recipients"

next click the boxes next to the contacts you want to send it to and then select "done" at the bottom.
