If help is needed in any aspect of this I'd volunteer as well. I already update, add, remove youtube videos to any entry I visit if it needs it. I even take the time to find a real video of the game before entering a MAME video (usually that comes second for better gameplay quality).
Many have offered in the past to sign on as a maintainer....
Bout the only thing you can do is add a youtube video to an existing entry. I've added vids to 5 listings that had nothing. I submitted sweet pics to a game listing that only has a grainy black & white catalog scan for the cabinet image (bout 18 months ago) and currently no change to game listing.
I would love to take more pictures and videos of the other stuff I have for listings that don't have photos/vids at all. I also have 3 working wall games with no data base entry that I could contribute pics and vids for, but meh. I would be more than happy to invest some time into documenting stuff without it sitting in some "approval limbo" by the site owners.
He's too busy playing the games he's hoarded away from the rest of the world to care about what happens here... as long as the newbs couple of dollars roll in without requiring any work, why the hell would he actually do anything to make this place better?
Greg needs to just turn over the forums to someone that actually cares, he can still cash the checks...
