Hey you stole my line! [;)]. Its true, better known designers will get rates earlier than others, but if you want a file to be rated:
-Post something you actually put effort into.
-Post a screenie so we know if it looks interesting enough to download, and make it nice looking, not like a pic of the restraint. Presentation is everything.
-Dont ask for rates, in most cases members get annoyed and then dont rate in the future.
-Be patient and wait for rates, sometimes it may take a day or two.
-Post an "advertisement" in the Track Advertisement section.
Try doing these things first, I garuntee that you will get some rates pretty early on. If you post a link to the ride I may give it a spin in the editor, but my simulator aint working ATM, so I really cant rate it for ya.
