[nag] Reminders for task events

[keyser]

I have a shared task list (and calendar) between me and several other 
users.  I would like the alarm on the task to send notice to all users 
who are sharing the task list.  Is this possible?

I have not been able to get the alarm to work for any task.  These does 
not seem to be a reminder.php as there is with the calendar app.

How can I gat the task alarm to activate?

Thanks!
