Publisher produces static pages and does not support dynamic functions such
as this directly. A guestbook is generally a script, which is usually
provided by your host and written in a language such as Perl, php, asp etc.
Many free guestbook hosts and scripts exist. You could goggle: http://www.google.com/search?hl=en&...snum=1&ct=broad-revision&cd=5&ved=0CDkQ1QIoBA
Or look on your webhost for what guestbook scripts they provide and support
and then you may be able to use the Insert > html code fragment to
incorporate the script into your site.
