Hi Christian,
What most sites do is to keep track of the latest time that a user requested
a page (ie when a page is requested store the current time).
Then a definitiion of "logged-in" is made.... usually this is "has requested
a page in the last 30 minutes" so the query to count the users whose time of
last access was within 30 mins of now.
Hope this makes sense,
Tom
