To
modify or remove an alert, click the Modify My Alert Settings link that
was sent to you by that alert. Doing so opens the site where that alert
was created, in the alert management screen.
On this screen, shown in Figure 1,
you can either click an alert to change its settings (such as when it
should send the email or what changes it should alert on) or select the
alert and delete it using the Delete Selected Alerts button.
