I was sent this site through one of the groups I am affiliated with, and found it to be a very consise site disseminating information on animal rights and has some very good tips on how to address the media, or anyone you write letters to.

. "This is a site dedicated to changing the world for animals by influencing the media to print, publish and produce more fact-based pro-animal material,"

I have included the link, and it is well worth the visit.
