Starting on July 15, the day that the Mozilla Foundation was created, we ask that you tell just one person who doesn’t use Firefox why you think they should, why you do. Share Firefox with a friend. If your friend downloads Firefox before September 15, you’ll both be immortalized in Firefox 2.

Great idea to spread firefox :) the thing is, i'm having a problem finding a friend that would be interested in downloading it =$ They either already have it, or don't care about changing their browser.
