I know I'm new, so I wanted to make a good impression. I was reading John Chow and he had a post on article directories. He listed 8 sites you can post for free? (Maybe this has already been posted here before?? If so, could a moderator delete this.) He says they are PR4 sites?
moneylearningcenter.com – Finance
openpoetry.com – Education
doccheysnoodlehouse.com – Travel
sovereignartists.com – Consumer Products
mind-brain.com/ – Health
prosandhackersclub.com – Technology

magem.org – Internet Marketing
Hope this helps with link building.
