There is no built-in capability in Publisher. You might look to your host to
see if they have a guestbook program, and it is possible that you could then
insert the html code into a Publisher page, but I haven't seen an example of
this. Its also possible that you could create the guestbook page using the
host program, and link to it from your Publisher pages. In general if you
want a dynamic site, you should use other software.
