"By filling out the Facebook client username form,
there’s a good chance that you’ll get the username back. Both Darren
Rowse of Problogger and the team at CDBaby were able to get their
usernames back relatively quickly after filling in the form. Getting
your username taken can be a big deal especially if someone else is
looking to build a reputation using a brand name that you’ve spent a
long time building."
Good to know they are doing this. They have done a nice job with the roll out of the IDs.
