When I go to
http://www.facebook.com/username/, I select my page from the drop down list and enter my desired username.
The problem is that Facebook says the username I want to use is not available. I did try to check if it was in use by visiting
facebook.com/myDesiredUsername buy I got an error message saying:
Sorry, this page isn't available
The link you followed may be broken, or the page may have been removed
If I try any other suggested usernames they all are available. How can I get the username I want if it does't appear to be in use by anybody else?
