You can download the beta from here. There are tons of cool new features in beta, including:
- Set Status Before Logon: See who’s online before others know you’ve logged in by setting your status! Subsequent logons can start you up in stealth mode.
- Winks: Send animations with sound to really get some attention.
- Drag and Drop Backgrounds: Drag it to your MSN Messenger window to set it as your background.
- Nudge: Tired of being ignored? Send a nudge to really grab someone’s attention. (My favorite new feature.)
