updown
I don’t go in for much of these social-network things (having slightly misanthropic tendencies), but here’s one I’ve gotten into: The UpDown, a community based on stocks and investing. You sign up and get a million “dollars” of fake money1 which you then invest in various stocks of your choosing to try to beat the S&P 500. The “social” part of it comes in where you can write your own analyses of stocks.
It could use some features — you can’t “buy” options on stock2, nor can you “buy” forwards or commodity futures. It’s still interesting. My “portfolio” is still small, and I only started it a week ago, but I’m hovering right around the break-even point.

You might want to look into trading futures. I have been working with futures for some years now and I love it. The secret is to work with an efficient platform…I suggest working with x trader or metatrader for forex… There is plenty of money to be made. Thanks, Rob.
