Randomly chosen testimonials:
I'm a professional cellist, and I have a study book of about a thousand short technical exercises. I use your site like the sax player, Jeff, to pick a few at random to work on when I practise, so that I'm always working on a different aspect of my playing. It helps keep my music fresh.
—Jonathan Draper, UK
Just wanted to send you a thank you for the random number website. Random.org was the perfect solution for us. We use your site to randomly select monthly winners for our free AT&T prepaid phone card contest.
—Kevin Waite, President, InstaPhoneCard, USA
