I'd simply like to say that hopefully this HP doesn't become the never ending class

In the books and the movies class time is perhaps 10% of the settings in the story but I've noted that many HP rp seem to be almost locked into class time
Who wants to be stuck in the same class for two weeks?
In the books Harry, Ron an Hermione are only seen in class when the course is a focus on their talents or shortcomings; also as comic relief (Wingardium Leviosa, Bang!)
Heck they are shown almost as frequently at the dinning tables as they are in class

As for student foes I am a fan of the Accidental Enemy archetype ( Think Warren Peace in Sky High )
