Zone Coaster's Guestbook is a script to allow a single user or multiple users to keep guestbooks for their websites. It was designed with the creation of nice-looking guestbooks in mind. If a form field is left blank and it isn't a mandatory field, it isn't printed into the guestbook. The owner of the guestbook can add his or her own fields to the fill-out form and they will be printed when the form is filled out. The bullet to use for each entry and the separator to use between entries are customizable through hidden form fields. All of this makes for a truly customizable guestbook.
