Hello, I'm planning to change my URLs from this format: www.mydomain.com/?id=12345&title=page+title to www.mydomain.com/page_title I learned how to do that with .htaccess, but the problem is I've been link building for the previous URL format. Now, if I change the URL pattern, Google will see it as a new page and start with PR0. How can I "transfer" possible PR to new urls? (pages will remain the same) Any help greatly appreciated. Thanks,
