I just joined here, a few weeks ago with the invitation from one of my friends from another site. At first, i was quite confused and not sure how to earn from here. After spending a few days in this site, it seems quite easy to earn in here. Most important is, try to get yourself familiar with the earning process by checking out the FAQ in this site. Here, you can get paid either through Paypal or Alertpay.
If you are interested to join, you can join from here. Hope you enjoy it.
