FOREX
I myself have never used FOREX, however I have heard alot of good things about it. I've had a friend who has used it and made money from it, and he has friends who do it and make money. What FOREX is for those of you who haven't heard of it, it is a currency trading website. Its like playing the stock market but your stocks are other currencies. Its a gamble to do, you may lose money but if you are interested in investing/trading this is a good way to try it out. My friend made about $1500 a month doing this. Which isn't a bad take home at all.
