Ok, here's the thing. I want to start thinking about investing in the stock market. The problem is I have no idea about it.

Second of all, I'm not a US citizen nor resident, can this keep me from investing in US companies?

Are there any resources that can teach me how to intelligently start investing money in this market? how much do I need, how do I do it (specially via internet)? Any experiences?

Or, better yet, what do you guys do with your money (i'm not talking about spending it in beer and stripclubs, but investments)? I don't want to earn quick money, but start learning about investing...specially because I still don't have too much money to invest

Anyway, any tips are appreciated.
