Al you need to do when displaying the 'users online' info is getting al profiles with the 'last seen' record on a time between now and x minutes ago (depending on what you consider to be an 'online' user). If you're using a database like mysql or postgresql for profile storage, use a field type that the database software can handle internaly, this can speed up the query. regards, Ewout -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
