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.

My group at the US Environmental Protection Agency (EPA) is required by law to conduct audits of randomly selected facilities. I utilize Random.org for the selection process; the format of the query page is well suited to our needs. Until I found (stumbled upon via Google) your website, the recommended procedure for ‘random selection’ was to go down the list of items selecting every nth one; actually these items are industrial or municipal facilities which store/use more than a minimum quantity of a chemical from a list of 140 chemicals selected for their toxic/flammable and dispersable properties. I found this methodology a statistical embarrassment; Random.org made it acceptable, and defensible, such as when a facility responds ‘why me?’
