I'm not using it, either. For me, it lacks two very important features.
1) Driver has a preferred/favorite car. This allows the car and driver to move from place to place together. As it is, it's only suitable for IROC racing, where the drivers rotate through cars/lanes that remain the same.
2) A "Season" needs to be added so that multiple race meets can be easily summed for a season (what I normally call a series) of series races (what I would call events).
There are a lot of other "would be nice", such as all the things Gio suggests above, but those are the two that keep DRAWW from using it.
