What does this mean?
Previously you needed to get 25 “likes” before you could claim a vanity url. So you created a page and it would look like this http://www.facebook.com/profile.php?id=6127*4#&re ? until you got 25 people to “like” your page.
After you got 25 “likes” then you could rename your page so it looked like this www.facebook.com/sunshinecoastsocialmedia
Not sure why it was ever done this way, except to say it may have stopped people taking names of which they have no intention of ever using.
