In MOSS 2007, I have created a Task list and selected the option of Alert Me,
and given mail address and selected necessary options. I got the immediate mail
saying I have subscribed for the alerts for the Task List.

After that, even though, I add, edit or delete any item in Task list, I am not
getting any alerts to me. I have tried this using couple of users but no luck.

pleae help me in this, am I missing any steps in setting up Alerts for a list.
