Setup a guestbook for your website with this free PHP script. If you want to know what your visitors think about your website this is the perfect guest book for you. Guestbook doesn't require a MySQL database to run. You can set it up to process smileys, it can send you an e-mail notification when someone signs your guestbook and you can delete inappropriate messages. Visitors can even post private guest book messages which only you can read! This guestbook comes with a bad words filter which replaces all bad words with **** in new posts and a secuirty switch which prevents floading (submiting the same message multiple times in your guest book)!
