I am a HUGE fan of Craigslist.org, and was pleasantly amused when I read that Craigslist.org had the first commercial beamed into outer space, hahah. http://www.cnn.com/2005/TECH/space/03/23/craigslist.space/index.html
In that article, it had a link to another company called http://www.talktoaliens.com/ You can now broadcast your emails or even a phone call to outer space.
So hmmm....have a bone to pick with God? Give talktoaliens a call, and for only $3.95 a minute you can give him a piece of your mind...and if God doesn't exist (or lets your call go to vmail) ET or Marvin the Martian may pick up your message and get back to you later.
What would YOUR message be?
