I would like to know how to add games to the games directory. I have a large backlog of saves/trainers/hacks/reviews/guides/ect. for games not listed in the directory!

Noted, although, I'm a bit bummed that it can't be manually inputted through a more direct means without scripts.

Just my two cents, I like scripts and though it isn't very direct, simply loading a game is a fantastically simple way to add a game to the database. Not to negate pengu's wishes, but feel free to work on more important things :P
The only problem I have with the script way of loading is I sometimes look at the newest games added to Kongregate, many of which aren't worthy of the name "game", and would rather not add them to the database when I'm checking them out, rating them, etc. But that was an easy fix by loading iframe through a chat command instead of automatically.
