I have A yahoo email a msn mail can i get anything to view those mails at the same time for free?

Yahoo and MSN are free email sites--the only way you can view them at the same time is make use of tabbed browsing and sign into Yahoo on 1 tab and MSN on the other and view them concurrently. If you want to only have 1 email, then send everyone in your address book in the other site a notice that they should email you at the 1st site. You can also forward your emails from 1 site to the other, I believe, but I'm not sure how you do that.
