The rules were clear: make a 4 x 6 postcard, be brief, be legible, be creative - let the postcard be your canvas.

The results were amazing: PostSecret.blogspot.com became one of the most popular blogs of all time, currently in the Top 10 of 54 million blogs. And people poured their hearts out in some very touching, sad, troubling, and beautiful secrets. Last Christmas they created a book of some of the best postcards and this winter it looks like there's another coming out.

Tonight get a chance to meet Frank Warren, the genius behind it all at Vroman's in Pasadena. Get your book signed, and know that the profits for the books go to a suicide hotline charity.
