Hey everyone! I stumbled upon this site/game and decided to give it go. It seems pretty cool and now I'm just trying to figure it all out! I have a question though, I accepted one of those mission things from Officer Jenny, how do I track it or check it? I am supposed to hunt Rattata and collect something off them and she said I would have a better chance at collecting it if I had a pokemon with a certain skill (like Mankey) which I don't have. I have been trying to catch a Mankey but I can't find one so I just wanted to go do this mission, can I do it without having a pokemon with whatever skill she said (i honestly can't remember LOL).
