These are some of the 'get paid' programs that I personally use.
InBox Cash - Inbox Cash sends you targeted e-mail based on your profile and location, earn up to $10 per e-mail. Earn $10 every time someone you refer signs up, too!
ePilot - one click to everything you need on the Internet and more!
AllAdvantage - The original get paid to surf program. This is a great program that I am doing very well with. I highly recommend it!
DesktopHorizon - Earn Desktop Horizon Credit Dollars (DHCD) while you surf. Each DHCD is presumably equivalent to 1 cent, that can be redeemed for cash or merchandise.
GoToWorld - You will be paid for using the internet, and also for internet usage of the people that you refer.
ValuePay - With Valuepay, you will earn 50% of the revenues for the banners you view, plus 10% of your direct referrals direct revenue (which is essentially 5% of the revenue that they generate for Valuepay), plus 5% of your indirects revenue (or 2.5% of Valuepay's earnings for those individuals).
MaxRef - This is not a get paid program in and of itself, however, you can sign up for all the above programs and many, many more at MaxRef. You are given a website to direct people to, which makes it easier to make new referrals to all your get paid programs.
