That's a great list and I will definitely have to check a lot of those out. Thank you! I do mypoints and NFO and I love them both. A few others that are completely ligitimate are:www.your2cents.com
which are much like NFO. They send surveys to you when they have ones that pertain to the info that you've provided to the sites about yourself. They pay by check. Your2cents rewards you directly with cash, whereas opinionoutpost gives points, but 10 points equals one dollar so they add up quickly.
Doing surveys is a really nice and easy way to make extra money, it's helping me pay for Christmas this year.
Another good site is Treasure Trooper. It's a lot like mypoints but they pay cash instead of points. They pay .75 per survey that you complete, as well as pay you up to $35 to complete various offers from doing trial offers of services like Blockbuster Online, as well as signing up for paid survey websites, and entering contests. Also, they give you a percentage back on your shopping if you shop online through their website. In my first two weeks there I've earned over $100. It's fun to because they turn it into a game with treasure hunts, and you earn coins and jewels and stuff. It's different, but it's a lot of fun and really rewarding.
