im new to wordpress, i made an account and created a blog named vietgamer.wordpress.com however, i do not like the name and want to change it. but i;ve heard that i cannot change the name of the blog once i've made it. i was told to export the content on that blog then create a new blog and import the the stuff there.
but how can i make another blog domain? i tried using the "add a new domain" in my account setting but it does not work. please help
