OK well Pinecone Research is one of the most respected and profitable survey sites on the internet. It is also very hard to get into because the only way to become a member is by finding one of their banners on a site and clicking on it. Usually these are in short supply but recently on Yuwie they have been popping up everyday. The only problem is that you have to be 18 to sign up. However, 18 is still a teen :D and if you aren't 18 you can atleast tell your parents about this great money making opportunity for them.
So visit Yuwie and find one of the ads
