VisitorLog

When you're logged into your website as the administrator, you'll be able to access an online real-time VisitorLog.  It automatically updates itself once per minute to show you who's online and where they are on your site.  The VisitorLog is fully searchable and you can delete entries through the browser too.

Check out this VisitorLog sample to see what it looks like.  All the links (except the referrers) have been disabled for the purposes of the demo.

From the VisitorLog you can also link to your site's stats page; you can view a stats page sample too.
