Ashketchup92

Hey Guys, i have some questions and didn't find answers in this forum: 1) Are there some Guys from Germany? It's much easier to communicate in mother language.. 2) is there a wiki or something where i can find all commands? Like chat commands.. How i can private messaging somebody? Or trade? 3) Why some People are yellow and others are not? 4) i want to trade my Haunter (lvl 92) for getting Gengar and my Kadabra (lvl 80) for getting Alakazam.. but i'm scared about getting scammed.. how i can find a trustworthy person? Actually i'm at Kanto E4.. Thanks a lot
