As you have probably heard, this weekend Facebook is opening up the flood gates and allowing people to register their 'name' or URL for their profiles and pages. According to Facebook, these new 'usernames' will be only available in basic text format, and account owners can only secure a single username for each profile and a single username for each page they administer.
They also have offered precautions for the names you choose, as "once it's been selected, you won't be able to change or transfer it" and to prevent name squatting.
Either way, be ready at midnight June 13th to get your name for your profile and pages, 'cause they won't last long...'
