I have now been paid twice by Mindfield and SimpleGPT.
SimpleGPT is a get paid to site. You are paid to complete free offers and fill out surveys. This is the best GPT site that I have found to date. In my opinion it is much better than other "top" sites like cashcrate. I feel that SimpleGPT is better because it has instant paypal, there is almost always help available in the chatbox should you have a question, and Doug (the admin) is always running either a referral contest or offer completion contest (sometimes both) for cash prizes.
To date I have earned almost $110 with SimpleGPT and have only been a member for about 6 weeks now.
