(CNN) -- In "Harry Potter and the Order of the Phoenix," the threat from villainous Lord Voldemort is ignored until it's almost too late. "Harry and his friends start Dumbledore's army to bring awareness to this," said iReporter Andrew Slack. "Meanwhile, our world ignores AIDS, Darfur and global warming." Harry Potter Alliance members attend a midnight screening in Burlington, Massachusetts. Some Potter fans, under the leadership of Slack, have come together to bring the spirit of "Dumbledore's army" to life. Slack is the executive director of the Harry Potter Alliance, a nonprofit organization dedicated to engaging Potter fans in social activism.
