In the game, when you select the "WipEout-Game.com" option, you access the site, and if you wish you are able to log in. Afterwards, you will be on the skins download page. Don't go anywhere, there is some text between the blue tabs and the gray window. One of these links is "Upload Profile". Make sure you allow all the plugins to run, and it will upload. Records will take some time before being updated though.
