Guys, guys, the process of trade is really simple if done correctly. I've been trading for a while now, and have experienced the joys of trading with passerby's and acquaintances. I engage in shiny trading, and it's really like experiencing the joys of facing a shiny in the wild, when you see it up in your screen and you offer another shiny for it that you do not want. It's the same thing for "normal-pokemon" trading. All you have to do is dedicate one box, to pokémon that you do not want, and bring them all to the name changer fellow, and type in your message in your preferred language. For example, my pokemon are named: Greetings (Zigzagoon), Sorry, I GTG (Sunkern), Thanks for trade (Bellsprout), No thanks (Wurmple), Yes please! (Rattata), I have it...(Machop), and so on. (Bracketed names are the pokemon named the message on the left of bracket).
Three advantages of this process:
1. Saves you time and displays professional trading etiquette.
2. It's a one time process (unless you trade your message pokemon away)
3. Prevents flooding of the Wonder Trade with "useless" pokemon (relative to player experience). Imagine if everyone playing pokémon saves at least 1 box of "useless" pokemon...Could reduce the cancer you receive once you wonder trade a shiny legend (Yes, I've been there).
