I also noticed that on the list of users viewing a page, if I manually logout I stay on the list even after a fifteen minute interval. This might be a bug you might want to check.

It likely follows the same logic for the main Who's Online, which also tracks users in the past 15 minutes. Perhaps a small designator, same as the [code]XX Users Online (within 15 min)[/code] label on the main page, would be useful.
