Facebook pages are a great way to run community and fan pages and also to offer discussion forums.
Facebook gives options to customize the pages to whatever we want, but there is a restriction on changing facebook page name.
Facebook page name can’t be changed once the fans / users count reaches 100. So you can’t change the name of the group once the page fans are 100 or more.
Facebook says:
Changing your Page’s name
This editing option is only available if fewer than 100 people like your page. More information can be found here: http://www.facebook.com/help/?faq=15196
How to change the name of the group then? You will have to delete extra members (probably if you have only a few members over 100) or else you will have to create a new fan page !
So when making a facebook page, make sure you have created the right name for it so that you don’t have to suffer later!
