Can I request a guestbook script (something similar to CeleronDude's) that can be easily incorporated in your existing page layout using "include( )" code?

I use his for my baby's website but it is flooded with spam post everyday from people who want to enlarge certain parts of my body and what-not (I'm sure you're tired of those too)...

I think maybe having to input an alpha-numeric value that you see may help protect a guestbook script -- but I don't know how to do that...

Thanks!
