Wes i don't want to be a jerk or anything, but maybe if you don't understand the plot and your having a few difficulties, then maybe you shouldn't join this roleplay man. To be a good roleplayer, you need to learn to not only choose the newest, popular roleplay, you have to also be ok with the roleplay and understand the plot you are going for.
If i got the plot correctly, It's gunna be played as a normal Pokemon plot, Team rocket is kidnapping pokemon and the Trainers [roleplayers that joined this] will be unaware and go against Team rocket, with their pokemon with the ability to change into human form. The plot is rather complex-simple and is actually quite a difficult roleplay to jump into Wes... but i'm not saying you cannot do it, I'm just saying if your not ok with the roleplay and you don't quite understand it, maybe you should consider walking away from this roleplay in the mean time... and later when you get the plot more you can jump in again [in reasoning and contacting Nami]
