[support] administrator: how can I force user log-off?

Hi, a few registered users on my web have some kind of auto-reload tweak in web-browser, which forces them to be "online" forewer. Is there any way to log them off manually (as administrator)? Or how could I prevent this behaviour? Jarry -- _______________________________________________________________ This mailbox accepts e-mails only from selected mailing-lists!
