Join the club. I hardly get any rates on my URDC coasters and I know the people who download them have URDC. WWS suggested sending a pm the members who download your rides to ask them to rate. It's worth a try.
same here for RCT3 rates, actually I get some but it's not very frequently.It seems that most people who own RCT3 and our on WWS just joined so they could download, and not interact with other members by rating ot posting in the forums.
Yea, I uploaded my best park. People downloaded it but they never rated it. The reason I uploaded it was to see what improvments that I could make on it.
