The GuestBook applet provides a zone where visitors can send you a message by email. Once you have received the mail you decide or not to put the messages in the file "guestbook.txt". The applet displays the messages in this file.
Important Note: This applet won't work if your web server doesn't host a mail server too. Try the EmailSender applet online, send an email and read the messages in the bottom output area. Then read the EmailSender help file.
