it works the same as every other sim to upload.
go to exchange and then upload ride, Enter ride name, simulation, ride info, maybe screenshot, and as final the trackfile. Then upload and wait till process is done, then look if the ride is uploaded right and wait for ratings. Actually pretty easy.[:)]
