UPDATE: I just successfully grabbed my personal Facebook url (facebook.com/bruce.houghton) with no problem. It took seconds.
Beginning Saturday June 13th at `12.01 AM EST (4:02 AM GST) registered Facebook users can current their current Facebook generated random url for one that more closely resembles their name.
The new usernames are limited to alphanumeric characters or a period
(".") and must be at least 5 characters long. So custom urls will look something like www.facebook.com/john.smith. or maybe www.facebook.com/yourband.com . While the change isn't mandatory yet, Facebook has
200 million users, so if you don't gab your url now someone else might. There is a mechanism to dispute the urls of trademark names, but who wants to go through that hassle.
Get you Facebook URL now at http://www.facebook.com/username/.
