It was a pleasure using your extremely quick and efficient random number generator service.
I'm currently using it to assign authentication codes to the users of my PBX system, so I know who's authorized to make international calls, etc. I was facing the problem that if I started assigning authentication codes in serial order, people might guess others' authentication codes and misuse them.
I wish to thank you for putting up this free service for the use of one-shot users like me, I really appreciate it.
