Hello there you two, welcome!
Twitch, since you seem to be interested in the challenges why not check out the Challenges section on PC where you can not only create challenges but also participate in existing ones.
And Anti, nice avatar I have to say. I love Twilight Sparkle, she's so cute and did you hear about her becoming an alicorn at the end of the latest season? Nice to see you're playing Black 2, it's one of my personal fave Pokemon games as well! I'll probably be seeing you around the Fifth Generation Gaming section on PC where you'll find some good B2/W2 topics.
Have fun guys and if you ever need a friend I'll be happy to help you out!
