Create A Forum - Support Forums

Hi
 
I have noticed that in some forums I belong My profile shows under Notifications as this:
 
[ ]  Receive forum newsletters, announcements and important notifications by email.

[ ]  Turn notification on when you post or reply to a topic.

[ ]  When sending notification of a reply to a topic, send the post in the email (but please don't reply to these emails.)

For topics and boards I've requested notification on, notify me:  [Instantly Instantly - but only for the first unread reply Daily Weekly ]

For topics and boards I've requested notification on, notify me of:  Replies and moderation Moderation only if I started the topic Only replies Nothing at all

At my own forum it shows without the top one viz  Receive forum newsletters, announcements and important notifications by email.

   Why is that this field is not showing on my forum?
 
My forum is http://thenewretreat.createaforum.com
 
Am I missing something? Is it possible I am 'not up to date?
 
I tried adding it as a Custom Profile however there is no way to place it under notifications.
 
Sure hope some one is able to help.
 
Thanks and regards
