How do I get my 'new' email address become the default one when I compose messages?

Yahoo beta gave the option of adding an additional address to the same account. I want this new one to become my default one when I compse messages. When you compose a message the email address defaults to the old return address unless you click on drop down menu to your new address. Thanx.

Click on the "Options" link in the upper right corner of Yahoo Mail; click the "Mail Addresses" link; choose the email address from the list that you'd like to be the default; finally click the "Make Default" link to the right of the list.
