"new kid" is being used to refer to somebody who is new to the community, it's not an uncommon usage of the term amongst social groups when a new person joins. "be nice to the new kid" simply means he should be on best behavior until the QueenCupcake (someone who has only been on the wiki for a couple days, and may be intimidated by agressive behavior) acclimates.

My inference that they may be a kid is based on the fact they were concerned with the minimum age necesarry to watch the show; something most teenagers or adults would generally not be very concerned about; as well as the questionable grammar and spelling.
