I think that the biggest problem is that people don't know where replacement players are needed. If anyone doesn't advertise the empty spots, nobody is going to fill them. Advertising an open spot can be a lot of trouble. PBW needs to list all open spots the same way it lists open games.

Let me explain a little bit. First we have a game that has started. Then a player drops out. After that the game owner has to decide if the spot should be filled again. If the game owner wants it filled, he/she just clicks a button and the open spot is added to the list. That way any potential replacement players can see open spots and their game information easily. When someone fills the spot, it vanishes from the list and everything is fine again.
