Sort Waiting Games From Most Recently Joined> Least Recently

Concise description:
Have the waiting games list start with the games that have been most recently joined at the top of the list and the least recently joined at the end.
Specifics/Details:
When a game is joined by another player, it sends the game to the top of the list. I'm not sure what this would entail tech-wise but it would obviously cause a lot of refreshing. Games created soonest would still start at the top of the list but would be bumped down as soon as another game had another player join it.
How this will benefit the site and/or other comments:

How this will benefit the site and/or other comments:
- Bring the more popular/active games to the top of the list, in turn causing all games to fill faster.
- Send the unpopular/stagnant games to the bottom of the list where they belong, counteracting clogging of aforementioned list.
