Nobody really knows how yet.
As for your side note, you should see if your friend would be willing to upload them themselves since it's best to have the original ripper do the submitting when feasible. Regardless, if the game doesn't have a section yet it just means we don't have any ripped models for it at current time. If you want to submit to a game that isn't presently found on the site, you'll just need to create a game section though the submission system before submitting the actual models.
(To add a game just click the game icon with the pretty green plus)
Just don't make a game section and not submit any content. Empty games will be deleted.
