How do I change my public display name on Yahoo mail? when I send mail, it's received with my name misspelled?

People receiving your emails, will see whatever is entered on the "from line setting", in options. So----Just go in and change/correct the "from line" setting, in Yahoo. 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 correct the spelling ---OR whatever you want----THEN click "save" changes at the top of that page. ......................................… You CAN'T leave that line blank. 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 ??
