Ther are two places where you could do this. One is ask crankeye but he has limited size requirement. He basically won't take a game over 5mb or 10mb. To contact crankeye, pm him.
2nd place where you could get gaming hosting is rios-ent, there is one requirement thou, you must join the rios-ent forums and post once in a while but thats it. Rios takes game from 1-100mb for full games and 1-50mb for demos. The way you could submit game to rios is thru Aol, Msn, Yahoo massenger or email to us in small chunks. If your interest in rios then you know what to do.
