Hi. Can someone please explain to me how the Wi-Fi connection thing works on the newer pokemon games like platinum/diamond/pearl and soul silver/heart gold. I don't know how to work the friend codes or the world union connection thing on the games. Can someone please explain it all to me? Also, people say (when I ask questions) do you wanna trade or swap. How is this possible if I can not meet the person. Also, how do I find out my friend code, because when i look, it says you need to set up wi-fi... but like i said earlier... i dont know how... please help 
the answer with the most information will get best answer! thanks...
