Tired of automated bots posting spam in your guestbook and want to put a stop to it? This is what you need. Silentum Guestbook is an easy-to-set-up guestbook system that uses a text file to hold the entries, so no MySQL is required. It can be up and running in a matter of minutes and integrated easily into any page. There are an abundance of spam-related words which, when detected, prevent the entry from being added. There is also a required 5 character verification image that needs to be repeated before posting to throw off almost all bots. If those prevention methods aren't enough, there's also a hidden checkbox field which, if checked, will stop the entry from going through. Since most bots complete every input field, they won't stand a chance. Five smiley images are included to add some eye candy to the page. The guestbook allows for an unlimited number of entries, divided into pages of five entries each.
