Playing With Yahoo Stock Trading

Did you know that Yahoo has their own stock trading program? It's too bad that they don't allow their members to trade for free; I would think their own stock would increase if they could figure out a way to recover any cost for them to offer such a service. My opinion about the service is kind of torn down the middle. I like a few of the options and the way they have navigation of the program set up however I think the service is kind of novice and it lacks advancement for better traders.
