Version 1.0 went live on February 24, 1998.
Version 1.1, which was released on October 10, 1998, added a few names to the characters list, explanations for more than five pluses or minuses, and a code for where you live. I removed the quote marks from INTERRUPT TRANSMISSION and RESUME TRANSMISSION, as they looked dumb within the code.
Version 1.2, released on January 10, 1999, added Vector Black and Commander Andy to the list of characters.
