If you have a Web site, you should really consider adding a guestbook. Guestbooks let your site's visitors leave comments and remarks. You can see from where and when people are looking at your page and also get valuable feedback. Guestbooks are one of the easiest ways to add interactivity to your site. Below are free services that will create and host your guestbook for you. In many cases, it's very easy to set up a guestbook with one of these services----you basically just fill out a form and you're up and running. For more Webmaster freebies, go here.
