Should I....

Should I make a THG RP?
I just went through this like two days ago, where I wanted to join a Harry Potter Role Play, but I didn't want to be extremely confused because so much has gone on between so many people and I would not want to be confused or make people mad at me.
So, tell me....
Should I make a Hunger Games Role Play?
And if so, what should it be about? Please describe it.
Thank you!
