I have created a fan page on face book, but now i want to change the page name, how can I change my fan page's name, and how many time we can change a page name.
If you are asking about changing the URL of your fan page, then just visit : facebook.com/username and you will be able to change it. However if you are asking the Fan page NAME, then it is not possible. Once you have created a fan page which already has likes or fans, then you cannot change the name and the category of the fan page.
