That's one of the ways to "fake out" this information. It still does 
not reflect the true "logged in users", but it's a useful approximation 
that works in most cases.

But that still doesn't allow you to somehow contact them from the 
server. You won't get around coding something that adds your message to 
the page the next time a user requests one.
