I am a high school English teacher and use Random.org in class on a weekly, sometimes daily basis. The ability to use the Sequence Generator to generate columns of random numbers is perfect for generating randomised seating plans or groups for project work. The Sequence Generator is also invaluable for creating a single list of 'turn order' for public speaking assignments or when conducting one-to-one interviews. As Random.org is able to generate the complete set of numbers instantly, this means that the students can observe the fairness of the process without it occupying valuable class time.

In several things that I do, I require some form of randomness (for example, secure primary keys for databases, with almost no chance of collision error). To do this, I use your site to create them. A simple generation of numbers between 0 and 35, and then change them into their base-36 equivalent, however long the sequence needs to be, and you have an virtually unguessable primary key sequence. You can’t guess what the next key in the sequence will be. Very useful for keeping people from being able to hack your customer list and finding out who does business with you (they might be able to guess one, but the next won’t be sequential, so they would have to start all over again to find the next). I also use it in my writing, to generate datasets for locations and people by assigning integers to various items and using the site to pick the ones that apply.
