Random: Guestbook question

[Always Hungry]

I know this is random, but I figured it fits this area of the forums.

Anyhow, I was wondering if anyone knows of a free guestbook
that can be integrated into one's website without linking to
another site.

I was searching for a friend to see if there were any out there
that wouldn't take the visitor away from the website and allow
them to leave comments and interact.

So far, I'm not having much luck in my search.

Any help is appreciated.

Thanks much.
