The Howler Campaign

Okay, everyone. Harry Potter needs your help. Pick up your quills and prepare to help Dumbledore's Army fight the good fight!
An absolute genius came up with the idea for the Howler Campaign, first mentioned here: http://hbpnojuly.blogspot.com/. As all HP fans found ourt, the Harry Potter and the Half Blood Prince movie's release date back from November 21st, 2009 to July 17th, 2009 in a pathetic, greedy attempt by Warner Brothers to have two major financial years and make more money. Online petitions are great, sure, but ultimately ineffective. But thousands upon thousands of bright red letters? That ought to make an impression.
So what do you say? Break out the Howlers! Write out your anger on some (preferably) red paper and put it in a (preferably) red envelope, then mail it off to Warner Brothers and help fight for your rights to see Harry Potter on the date that they promised.
Here's the address:
Warner Bros. 4000 Warner Blvd Burbank CA 91522 818-954-6000
Warner Bros. Studios 4000 Warner Blvd Burbank CA 91522 818-562-3062
Of course, there's a few rules I ought to point out. Number two is pretty optional, but otherwise the rules are really brilliant, come up with by a mixture of people. So please, PLEASE, to make this work really well, try and follow them. (Not being pushy, just a suggestion.)
1. Don't write anything that could come off as physically threatening.
2. Try and keep it short and not-so-sweet.
3. Write "HOWLER" at the top of the page.
4. DO NOT see the movie opening weekend if it is being released in July.
5. DO NOT go to repeat viewings if it is being released in July.
6. DO NOT see any other Warner Brothers movies.
7. DO NOT write anything childish or overly-rude. It just makes us all look bad.
Dumbledore's Army, I'm counting on you all to help us succeed in this. If we all ban together and work hard, we can do this. I know we can.
I'm sending about twenty.
Please, you guys. Harry needs help. So send out those Howlers, and save the Half Blood Prince!
