There plenty of sites for earning additional money online, and here is one for microworkers. It is a crowd sourcing site where you can solve simple tasks, click on ads, sign up in sites, vote for pictures, videos events, post in forums, yahoo answers and so on. Basically you do what the employers on the site ask you to and in return you can earn small sums of money. From 10 cents to 1$.
When you have reached a minimum payout, microworkers will mail you a pin code and the sum will be payed out via paypal. So yes it seems this site works well,
