Get short easy to remember Facebook Fanpage URLS

The default of Facebook fanpages is that when you start one you get a URL like this

http://www.facebook.com/home.php#!/pages/Truro-United-Kingdom/Wavelength-Magazine

however if you want something shorter and more cool like. 

http://www.facebook.com/Polzeath

then all you need to do is visit this page

www.facebook.com/username  and you can assign short names to your fanpages. 

ITS AS EASY AS THAT :))
