Facebook Vanity URL’s also for Pages
As of June 29, 2009 , Facebook fan pages with over 100 fans can now also get their customised/vanity url. To do this go to http://www.facebook.com/username/ and select the username for any fan pages that you administer.
As an example, a page that would originally have be fount at
http://new.facebook.com/pages/the-harcombe-diet/100265415
is now at
www.facebook.com/theharcombediet.
I like this feature. It makes it much easier to let people know about your fan page and to include it on marketing materials, press releases, email signatures and, of course, in conversation.
