I saw this and couldn't resist: halo.bungie.org has moved into the propaganda business with their Halo SETI promotion. I love their slogan... it's so perfect for the theme and topic. :)

For SETI folks new to this friendly rivalry, take a look at the Halo and Bungie team pages. Both are open teams, and new members are welcome to either. Fight the good fight with the underdog Halo team, or set your sights on world domination with the Bungie team... all in the name of science, of course.
