My notifications for anonymous users are not working consistently. When the user visits the site, clicks "Watch this page" and enters their email address, a notification is sent that they are watching the page. Since I changed the setting to send email notifications immediately rather than according to my cron, the anonymous user now gets the first notification of a page update. When the emails were sent based on cron, they were never sent. Now, with the emails being sent immediately, they receive only the first email of a page update. When the page is updated again, no email is received by that anonymous user.
