Homepage has PR, rest of site none

Ok, so having a robots.txt file is a good idea. Why not have one is what I'm taking from this.

However, this does not solve my problem as to why I'm not transferring PR ranking to internal pages. Internal pages are getting indexed and visisted, but no PR. Am I worrying about this too much?

Toolbar updates occur every 3 months. You won't see internal PR changes until the next one (which should be towards the end of Oct, early Nov)

Robots.txt disallowing the site lead to the main page being deindexed so it passed no PR to your site. Aside from all your pages I've checked have extensive duplicate content issues and that can get you a grey bar too.

It's pretty hard to diagnose any other problem with two such huge things impacting things.

Crap. Thanks for checking those PPP. I was hoping that people were submitting unique articles, but it seems not.

What is the best way that I can avoid this duplicate content issue? Run all articles through copyscape?
