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.

I wanted to both thank you for your random number generator and apologize for hogging the numbers today (I used up my quota and then went to my coworker's computer to get more numbers). I had to generate 50,000 random numbers for a project at work with only a couple hours' notice—we’re producing cards for a client as part of an instant win game, and each one needs a unique code—and your generator saved the day.

Plus, my coworkers already think I have mystical intellectual powers, and when I can come up with a solution like this in 15 minutes, it boggles their minds.

By the way, I love the user interface and the design of your site—it's simple and easy to use for non-mathematicians, and it has a nice clean, elegant feel to it.

Thanks again!
