This will not make you rich however, you can make a little extra money.

What you do is easy, first you make an account. Then you will log in to look at ads and they credit your account actual money. You will also need a paypal account for this, becasue that is how they pay. I just signed up and already have $4.90, but typically you will earn between .20-.50/day. Which I think is great just for looking at ads. You will not receive a lot of e-mails from them, which I actually think is great.
Some of the sites like My Points send you e-mails and you accumulate points by opening e-mail. If you would like to join My Points leave me a comment and I will send you an invite. (I would appreciate the referral points)
