How can i change the display name that appears when i send an email?

YAHOO! EMAIL (regular email, not 'Beta') To change your outgoing email name> >Go to your email box >click on 'Options' (upper right, horizontal list of options, blue letters) >scroll down to and click on 'General Preferences' (second column, blue letters) >scroll down to the 'Name and Email' section >change name in the 'From name: [_____________]' form >click on the 'Save' button (top left, under 'Mail' tab)

This works for Yahoo! Mail Beta: Adjusting the From field changes how your name appears in other peoples' incoming mail. You can also adjust the email address they will send a message to when they click Reply. Here is how to do it: 1.Click Options in the upper-right corner of your Mail page and select Mail Options. 2.From the list on the left, click Accounts. 3.Click Add or edit an account – it is toward the middle of the page. 4.In the box on the left, click Yahoo! Mail. 5.Click Edit. 6.In the From name: box, enter your name how you wouldd like it to appear in the From: line of your outgoing messages. This is the name people will see in their Inboxes for messages from you. 7.You can leave the Reply to: field blank, so your Yahoo! Mail address is automatically the return address when others reply to you. Or, you can specify a different return address by entering it after Reply to:. 8.Click Save to put your new settings into effect. Note: The From name field can not contain special characters like the @ symbol. And, the address in Reply to: can not exceed 40 characters. http://help.yahoo.com/l/us/yahoo/mail/yahoomail/basics/basics-20.html
