Duplicate content and blog content.

Hey there,

The WPMUDEV support dashboard is enabled.

Regarding a duplicate content issue. We watched a Matt Cutts video about 'no-follow' links - but it didn't address my particular issue. There seems to be duplicate content issues on the IDX search pages - and I need to know about making those pages 'no-follow'?

I also read that the blog posts come up in 4 or 5 different places on the site, which could create duplicate content. I understood that there was a WP setting that can help eliminate this problem?
