erm, i think this a great site and can't think of anything new it really needs. the design is superb, the stats and info cool, and the map and market place are great features. plus, you have news stuff off pinballnews.com (another great pinball site) . Between this , Pinballnews, and ipdb you dont really need anything else!!
it only needs to be populated a little more by pinballers!! they're either too shy to write, or they're too busy playing pinball!!
oooh, i thought of a new section for you. "people giving away pinball machines for FREE!" that would be a popular section!!! )
