I had the chance to grab this leaked copy of MSN Messenger 6 (Beta) for XP.

Right Click the picture above and 'Save Target As...'

Below are Screen shots I took to show you guys what it looks like.

This is the new Layout...

Below are the new Emoticons... I understand you can customize and make your own.

This option allows you to change the inner background of your MSN Messenger...

I'm sure if you guys download it... you'll find out quite easily how things work.

Enjoy!
