It's been 10 hours since Facebook opened the floodgates of its custom username url registration. In case you forgot, here's a reminder to pop over to www.facebook.com/username and chope your own facebook url.
I can almost hear a few "Oh shit, I forgot!" out there.
Do bear in mind, your choice is PERMANENT. That means you cannot change it, so don't do anything rash like register some nonsense name because you were angry that your name was taken. It is yours FOR LIFE and deleting your account will not place that name back into the pool.
I feel like I am signing some birth certificate in blood. Now Facebook owns me completely, dammit.
Chope early or you may end up with the Hotmail situation and be forced to call yourself Jane1984sg or something lame.
