Seomoz is showing duplicate page content for my wordpress blog

[RogersSEO]

Hi Everyone,

My seomoz crawl diagnostics is indicating that I have duplicate content issues in the wordpress blog section of my site located at:   http://www.cleversplash.com/blog/

What is the best strategy to deal with this?

Is there a plugin that can resolve this?

I really appreciate your help guys.

One common source of this problem is the tag, category, and author pages. I include these links in my blog because they're useful to site visitors, but I make sure to link them as NOFOLLOW to avoid the content duplication problems they can cause.

EDIT: I use the All in one SEO plugin for this. There are checkboxes to add NoIndex to those page types.
