help a newbie please

[fireman664]

Other than My retirement, I have never dabbled in the stock market. I am looking to take some of my poker winnings and "play around with online trading", as a way of learning the market. Since I know nothing, and will be learning as I go, I would like to use a site that allows a minnimum amount of money to invest and doesnt charge alot per trade. Any thoughts on a site I should look into, or anything else I might want or need to know. Thanks
