Peek-a-Boo is 窶彜hareWare with a Kick.窶 It's ShareWare because after using it for a couple weeks, if you find it useful enough to keep using, you are obligated to send in the ShareWare fee of $15. It has a kick because after you register it, you'll get a personalization code. Once Peek-a-Boo is personalized, you may freely distribute your personalized copy. When somebody else registers a copy that was until then registered to you (ie, you were directly responsible for distributing it to that person), I'll send $5 to you for helping distribute Peek-a-Boo. People have actually made money by registering Peek-a-Boo!
You can print out a registration form from Peek-a-Boo's About dialog. Just click the 窶弃rint Order Form窶 button, fill in the blanks, and mail it with $15 to me.
If you can't print out the order form for some reason, please include the following information with your money:
窶「 The name of the previously-registered person
窶「 The ID number of the previously-registered person
