How do i invite or add more contact to my yahoomail.?

[sillydog145]

I want to invite some friends on facebook and twitter who uses yahoo to my yahoomail contact.

I don't know if it works that way. But if those friends have their yahoomails on their pages, just copy and paste those to your contacts.

Yahoo's been redesigning everything with their yahoomail, so maybe there is an easier way to do that now: http://twistity.com/yahoo-mail-finally-redesigned/
