Well, let me ask you: if you don't read it much, why are you then so interested to help with games?
But if you are, you first need to contact Kosta through PM. Just click on his account name and select Private Message. Tell him you want to contribute games and he'll probably give you an account where you can upload the games to.
Btw., the games should be abandoned already and not sold anymore anywhere except E-Bay and Amazon and similar shops. Else they won't be put on the site.
