A guestbook page is a traditional web based guestbook where people can leave a public message on your site.
To create a guestbook page:
Click on New Page.
Select Other and then select Guestbook.
Give the page a title.
Your page is ready and includes a simple message form with a name field and a message field. Keep in mind that the guestbook messages left by your visitors will be public, unlike the contact form messages.
Find your guestbook messages
To view and eventually delete your guestbook messages:
Click on the Cogwheel Icon.
Then select Messages.
Go to the tab, Guestbook. In this area, you will find all your guestbook messages. If you want to delete a message, you can click on the Bin Icon.
