It would be nice if Phoca came with a default guestbook already present after installation since it took me a while to understand that I had to create an empty guestbook to get started. I didn't get a useful error message, just 404 page not found.
None the less Phoca easliy beats the other guestbooks I've tried due to
- Simple installation
- Native Joomla 1.5 support
- Backend settings actually work
- Wide language support
