There are too many of them actually and netizen like me is just puzzled about its true purpose and authenticity. Their promotional activity is almost the same and one would be attracted once he/she browse the websites’ dollar giveaways. A friend of mine referred me to some of these websites and after reading the agreement and other stuff, I hesitantly signed up. As a new member, I am still on a evaluation mode, taking it carefully whether it is not a scam or something that would give me problem later.
For the benefit of others I am sharing two of the websites that I think is risk free and worth trying. Please feel free to follow the links below.
