When your Facebook Fan page reaches 25 fans, Facebook allows you to create a specific URL for your page. To do it, you have to go at http://www.facebook.com/username
Once you are on this page, you will have to select the page you want for a specific URL. Once your page is selected, a box with the mention username will appear and you will have to put the name you want for your page. After, click on ‘Check Availibility’. If the name is available, a box letting you know it’s available will appear and then you will have to click ‘confirm’. If the name is not available, you will be able to chose another one.
This is an example of the URL for my Fan page : http://www.facebook.com/CareleBelanger
As for the username you will chose, try not to put any dashes or dots in between the words. Also, try to take the same name as your page. Before deciding on a name, make sure of the one you want because once you confirm it, it will be impossible to change it.
Why it is important to create a specific URL for your Fan Page? Because it will be easier for people to remember the exact address and also for you it will be easier to talk about your page to people.
To your success,
