Does anyone know where I can find a guest book for people to sign & make comments to put on my website?
Try your web host. They probably have one that you can use.
Otherwise, try webreference.com.
I am including the link to a web page I made. Scroll down to the bottom, you will see my guestbook. I got this from html gear What I love about it is, I could match it to my site.
Here is a link that might be useful: WJRS
