Battleships By Email (BBE)
Play battleships against an opponent via email! No database required as all information is passed along a URL.
A database is used in the script, however, to allow for recording of wins and losses.
One problem with this script is that Outlook's maximum querystring length seems to be 255 characters (or there abouts), and the URL created by this script is almost always longer than that. However, it works great with other mail clients such as Mozilla, Eudora, Pine, Elm, Mutt, etc.
