I've actually learned a few interesting things through answering some of these questions so not only do you make money but you learn things and could even have fun in the process. You do not need a cell phone just a computer with internet. They pay per question answered and you work whenever you want. I do a lot of this in my free time, whenever I'm home with some spare time I just log on and start answering. They are currently hiring and I don't know how long this opportunity will be available, they open and close registration when they need more guides.
