Note : To make things more difficult to follow as a beginner, the rules are changing at the end of April 2011 (the so-called Black and White rule changes), with the following change in terminology: all Trainers, Supporters, and Stadiums will now have the umbrella term Trainers, with former Trainers now becoming Trainer Items, Supporters becoming Trainer Supporters, and Stadiums becoming Trainer Stadiums. If you are just coming into the game, you will probably only ever know the new terminology, but be aware that everything you read that predates that change will use the old terms
