I'm not a basketball fan, but I know that March Madness fever is sweeping the nation. Many folks are creating office pools for a little harmless wagering, and Office Pool 2007 makes it much easier to keep track of who is in, and how they are doing. It has a number of very cool features (FTP, a PHP based web wizard) though it lacks the polish that many Mac users are used to (though it is cross platform). A single user license costs $25 (if you use PayPal) while a company wide license costs $50.
Remember only bet cookies, since gambling is frowned upon here in the States.
