I want to move my blog to WordPress.org and use the import/export function. I don't wanna use domain mapping as it's going to be an extra cost for me, I just wanna start a new site and bring my old posts with me. But what happens to my backlinks and PR? will that follow me in my new address?
Also, what about the issue of duplicate content? won't my new site (or old site) be penalized because of duplicate contents?
The blog I need help with is chelltan.wordpress.com.
