Tell a chum!
Hey, thanks. Space Cows From Outer Space will be more fun if more people play.
Perhaps you could tweet about it? If you include the hash #spacecows it will show on the main page. Or post about it on your favorite forum? Or stick it on your blog?
Maybe you could even do a review of it for your blog. That would be nice.
So, basically, what I'm trying to say is 'spread the word'.
What? Did you honestly expect me to do it for you?
