All our members and guests are not all job seekers, so it make no sense sending notifications to all members mail.
But those interested in receiving jobs notifications can activate it individually, by doing the follows,
We have six job boards from Monday to Saturday, you activate each board individually,
You click on Monday job board and you will see Notify | New Topic | Post new poll
You click on NOTIFY and a message will appear "Are you sure you wish to enable notification of topic for this board? you go down and click "OK"
You do the same with Tuesday Job Board to Saturday.
