Thank you for your help Tammy. I read through your links when you first replied and they helped a lot.
Pardon my lack of knowledge here, but I just want to make sure I understand correctly: If I go the rel=canonical route for the "duplicate" pages, it won't actually redirect the user, but will just tell google where the "original" page lives, and that it's duplicated on purpose correct? Does that then hurt the rankings for the site that's not showing as the "original" content?
Thanks again for your help.
