Think of Fresh Visits as KeepandShare's instant "visitor register," logging everyone who visits any of your shared information.
You simply click on any notification to instantly see the item your friend visited. You can then continue browsing using the browser's back button to return to the Dashboard and perhaps click on another Fresh link.
Every notification shows you:

If your friend was not logged into KeepandShare when they visited your information, they will show as "anonymous." This only happens when you have shared information with the "Public" group, since KeepandShare requires log in before granting access to any protected information.
Click on the "All Fresh Visits " to see a full report of all visits spanning back many months.
