Auto notification of replies

Is there a way to change to 'auto notify replies' if the initial posting was done with this switched on?

If you go to edit post via the pencil icon on the right side of your post, you can turn it off.

I'm not sure if you need a certain amount of rep/posts before this is available or not.

I am sorry. I should have made myself clearer.

I am aware that when a member submits a new posting to the forum, a checkbox is available to switch "on" so that the member is automatically notified of replies. Twice now, however, I forgot to switch this checkbox 'on' before I submitted my post. Is there a way a member can turn this feature 'on' for a posted question for a post that has been submitted?

Got it, thanks. I glossed over and missed it previously.
