It's pretty kewl, you get $1.00 to $8.00 for doing things like registering on to other websites and Nitroclicks will pay you just for registering. Most of the sites will allow you to unsubscribe later if you decide not to stay on, BUT you still keep the money you made for performing the task.
SUGGESTION: Set up a hotmail account so that you don't have to use your real email address and let hotmail get all the commercial stuff websites might send you for registering.
Here's a short blurb on the site:
Each of our members receives 22-26 emails per month containing 1 task each. They are usually simple tasks (asking to visit a website), or sometimes a little more complicated ones (asking to register on a particular website). Tasks are different each time and they are chosen according to member's personal interests. In addition each member has the ability to increase his(her) earnings by referring other people. Our members do not only get paid for direct referrals, but also for indirect ones, 5 levels deep.
Here's the kick, they won't pay you until you make $500.00.
Many of our members fail to achieve as much as $500.00 USD, giving up in the middle of the way, so the money they have earned remains with Nitroclicks. That is what compensates our high paying rate ($3.00 USD per task). The real cost of each task is much lower, so we would never be able to pay as much, if many of our members did not give up.
You've got nothing to lose for checking it out NitroClicks.
