I thought I would put together a short video tutorial on creating a username for your Facebook profile or Facebook fan page. Normally, for both, when you first sign up for either a profile or fan page, the URL structure is very generic and often has a long number.
For those who brand their user profiles online, the number can be a bit of a pain. However, it is only temporary. For profiles you may have to authenticate your account by cell phone to have use of this feature. For fan pages, you have to at least have 25 fans.
As a quick reference from the video. The link to the page to change your Facebook username or Facebook fan page is http://www.facebook.com/username/.
In the case you are having troubles with gaining fans, I might suggest participating in #FanPageFriday at both the Facebook fan pages of Nile Flores and Kim Castleberry. Just remember to also share the link to your favorite fan pages and then another wall post to your own fan page.
