I want to ask that how i can change my name when i send email to any one there is my 1st name?

You have to change the "from line" setting---(for outgoing emails). This works the same in both versions (Classic AND All New Mail). Mail page>>options>>mail options (or "more options" on the New Mail)>>Accounts (from the list on the left)>>then click on "Yahoo Mail"---(middle of page, under "Accounts"). Now you can erase whatever is showing, on the "From line" and type in something else---a nickname---or your own name---or whatever you want----THEN click "save" changes at the top of that page. You CAN NOT leave that line blank, otherwise Yahoo enters what was previously there or even sometimes puts "False" in place of a name. Some people say you have to log out and then back in, for the changes to be effective----but some find it's "not necessary"-----maybe it depends on your computer ??

The process has changed with Yahoo Updates. CHANGE "FROM" NAME IN YAHOO MAIL 1. Click on the "Options", Mail Options link in the upper right of your yahoo mail page. 2. Click Accounts in the column on the left. 3. Click on Yahoo Mail in the window that opens to the right. 4. Go to the box across from "From", click in the box, delete what you have in there, and enter a nickname, email address or whatever you would like displayed in outgoing mail. 5. Most important, go to the top left of this window and click the Save Changes icon.
