Yep and there was no PDT rule prior to the tech crash bear 2000-2001.I was recently asked how one should get started trading the emini - should the newb start with mini or micro? I said now that now that you can trade $0 commissions with with limit orders I'd reccomend a newb taking $25K and daytrading a 10 lot of SPY or QQQ at Schwab. Work up to 500 shares, and once you can do that effortlessly and without fear, then you are ready to trade a mini.
Of course, he complained he only had $5K. And you know, that shouldn't be a problem except for the PDT rule.
