It would probably be more realistic to add some kind of 'where' clause which counts only people active in the last N seconds/minutes, for MOST sessions. It all depends on your application's needs, of course, but most applications probably have sessions that live a fairly long time for the convenience of the user who walks away and comes back after not TOO long a time, but that person can not realistically be reported as "on-line" if you want an idea of how "active" the application is. I've seen several "chat" applications where I got sucked in to using them because there were people there -- only there really weren't any people there, and it was dead, dead, dead. Don't do that. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
