You Have Three Days To Pick Your Facebook Vanity URL, that is
Friday 12:01 AM Eastern Time. Choose Wisely, Or You’re Screwed LOL (j/k), not that I got any FB acct, but I got
twitter LOL.
Meaning from this, the current address:
facebook.com/profile.php?id=500065899 (no, that is not mine, I'm not caucasian LOL)
you can have your FB address like this for example:
- facebook.com/rosely
- facebook.com/GuGu
- facebook.com/TheBatman
- facebook.com/Lunatic
LOL
So make sure you don't sleep early on friday night coz it's first come first serve for the Vanity URL name that you choose. If it's taken then it's taken.
