Well if no one rates than what is the point of uploading? I'll just stick to CS where they do rate and appreciate something you just spent many, many hours on.
If you want him to post here more why not take it into your own hands and rate yourself GerstlCrazy? Can't hurt, can it? Helping a fellow member out by giving him some thoughts about his ride and showing you appreciated him uploading here, and at the same time helping ensure you'll be lucky enough to see more from him here.
