I'm having trouble uploading my water coaster designs.  I saved them, but when I go to find the file, it's not there.  I'm looking under Coaster Designs.  What am I doing wrong??

They should be in My Documents / RCT3 / Coasters...

Thanks for the uploading help. I love playing RCT3, but I also still love playing the first one. Is there any way to download coasters that other people have made for RCT, just like with RCT3? I'd love that!

Nope, if people wish to share their RCT or RCT2 creations, they must do it through the forums themselves. The download center is exclusively for RCT3, because that's what most people come here for
