I just wanted to let you know that and how I've used your delightful service. In the course of writing my thesis I needed to be able to randomly assign 15 items to five different categories and then randomly order the categories. I was going to use old fashioned D&D dice for the job but found your site and was able to do it in far less time! Thanks a lot, and you will be cited in my final document.
