Neville and the DA (Dumbledore's Army)

Hi! I've always wondered what was happening in Hogwarts when the Golden Trio were off on their legendary quest in the 7th book. What Neville described to Harry... I could imagine how epic and interesting 7th year Hogwarts WAS. I imagine it being 5th year Hogwarts ON STEROIDS. This is just a short story but if I receive enough enthusiasm, I will expand and write more :)
