Signatures of the members of Dumbledore's Army.

Dumbledore's Army is a group created by students who disagreed with Professor Umbridge's teaching methods.

Dumbledore's army first met at the Hog's Head where they thought nobody could overhear them. When an Order member happened to be at Hog's Head the same day and time they reported back to Albus Dumbledore.

Dumbledore's Army elected Harry as leader. They then met in the Room of Requirement and used coins to communicate the time and date of the next meeting. Ginny was the one who spoke up and said to name the group Dumbledore's Army because the Ministry of Magic did not like Dumbledore at that time. They sign their names and continue meeting until Marietta Edgecombe tells Professor Umbridge about the group, which resulted in Dumbledore escaping from the Ministry's grasp and Umbridge becomes Headmistress.

From the Story

"Dumbledore's Army, also known as the DA, is the secret group of students who gather to learn Defence Against the Dark Arts skills from Harry."

"The group gather in the Room of Requirement at Hogwarts to practise their spells. In the last lesson before the Easter holidays, the group practise the Patronus Charm. They are forced to disperse swiftly when Dobby arrives to warn Harry that Professor Umbridge is on her way to the Room of Requirement, having found out about the meeting that evening."
