If your method does not require any arguments, you can call it like
this:

<dtml-var "PARENTS[-1].GuestBook.addEntry()">

You can't omit the parentheses when using python expression syntax to
call a method.

Again, I would *strongly* suggest moving your application logic into
Python scripts instead. You'll find that Python is easier to learn than
you think, and the script objects will be much easier to write and
maintain than Python expressions in DTML tags.
