Lucky Fire, it's fine. I figured it was something like that anyway.
As for how The Challenge works? Basically you, along with the other members of your team, work towards a certain goal for the round that we give you. This can include activities such as drawing, problem-solving, Pokemon battles, chess, writing short stories...you name it, we can challenge you with it.
The best strategy for your team is to figure out who is the best person on your team for the job. Being decent at something is okay, but if you want to win, you want to put your best person forward. (Thus, if you want to be a help for your team, try to be proficient in as many things as you can.)
