I need to set up an additional email address, how do i do that?

Just set it up like your opening a new account.

Real easy. Just go to create screenname. You can get free email addresses from several sites...Yahoo, MSN, AOL. You can actually create as many email addresses as you want.

if you mean the sub-email addresses that yahoo offers, they should have ways to walk you through it - I had several for a long time, but haven't used them in more than a year. let me check - and you can, too - look in the Mail Options area. Okay - I checked, they don't have those anymore. But they do let you have one extra email address that delivers to the same box as your current one. Go to Mail Options, Management, Mail Addresses and then Extra Accounts. That'll set you up.
