Live Mail Beta sin invitación.
En computerhelpforum.org he encontrado este truquito para tener ya Live Mail beta. Que lo disfrutéis.

Alright, let’s start!

1) Open up Internet Explorer. MSN likes Internet Explorer, and hates Firefox. (Damn Microsoft!)
2) For this to work, you must be signed out of MSN. Go to the MSN Homepage, and double check you are signed out.
3) Copy this URL to Internet Explorer: Right Click On Here -> Copy
4) You should be redirected to another URL (Another URL to login). Sign in.
5) You should see the regular hotmail once signed in.
6) Once you see the regular hotmail, do Step #3 again. Copy the same URL above.
7) Click ‘Particpate’ on the bottom (Scroll down!) and walla!
