How do I make yahoo my default e-mail address?

When replying to my email others get the wrong email address?

• A friend trying to reply to my email message got an old email address in the to space. I have made yahoo my default eamil by joining messenger. What else can be done to make yahoo the reply address and the email for my pictures folders?

• Answer:

  Check your "reply to" setting and correct it. Mail page>>options (top right)>>scroll to and click on "general preferences". At the top of that page, under *Names and Emails* you will find the "reply to" line. Erase what is on that line----and leave it blank if you want the replies coming to your current address. Put a different address there ONLY if you want replies going somewhere else. Then click "save" at bottom of page. ??Using the New Mail ?? Mail page>>options>>mail options>>accounts (side panel)>>add/edit an account>>select Yahoo mail (side panel)>>edit>>general preferences--------change it and save it.
