I would suggest taking the time to secure your personal Facebook Username.
Facebook has launched Facebook Usernames and it’s been similar to the wild West land grabs. According to Mashable, on site at Facebook’s headquarters, in the first 3 minutes, there were 200,000 usernames registered and in 15 minutes, 500,000, and it continues to rapidly rise.
Starting on Friday, June 12th, at 11:01pm, you’ll be able to choose a username for your Facebook account to easily direct friends, family, and coworkers to your profile. Default choices are variation of your full name, but you can choose your own custom username. However, if someone else has taken it before you, you’re out of luck, so register your URL quickly.
To select your username, visit the link below after 11:01pm on June 12th:
