when the user surfs your pages you update their logged in timestamp then it's always updated with the last time they were asctive on your page, then you setup a cronjob or something else to check weather or not the users has been active in a given interval like 1 hour. This method will still have somekind of uncertainty. I still think there are many other ways (better?) to do it. -- Henrik Hansen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
