Anyway, what you do it draw things and send the picture back and forth. Its kind of like a drawing war, one person might draw a car, then another person draws a missle pointed at it, then the other person draws a tank shooting the missle or something. So anyways, I will start it out with providing a simple setting
Use Flash if you have it (I guess paint and photoshop are acceptable)
You must draw it, don't copy and past a picture of a tank, and if you use photoshop just use the brush, no effects
Make sure its 500 by 400 pixels
Thats about it for rules, and if you use flash then export it as a .png for best quality.
