Deadline - Assignment Object

Hi all,

I have few question regarding assignment object.

1. I understand that once the deadline is met, the notification will be send to the person that is assigned. Is this 1 time notification only ? Or will the notification be sent everyday until he/she complete the assignment ?

2. I understand that this deadline is set from the workflow configuration. For instance 2 or 3 days. However, is there a way we can do something like 2 working days ? This will exclude weekends. Any idea ?
