If the moderators have the ability to delete posts, that they delete games added to the database as it's redundant information unless it's useful, lowers the probability to zero of missed games which equals no complaining\asking from the dumpers that a page or two goes by without their game being added did it get over looked. This will also work for the fixes and addition part.
The second idea is to clean up the general discussion and take all pertinent and merge it into a coherent F.A.Q. of sorts, I believe it will look more professional to the new people and it will hopefully help them find the answer quicker and lower the chance of being asked multiple times.
