"Reason for Editing" posts

These used to be added to the post when you saved the edited copy. Now nothing appears. Is this a glitch, or was it meant to be deleted as a part of the post?

Tried to do it here, too. But do you see it?

It may depend on the amount of time between when you make the original post and try to do the editing..

(or not.... Seems to simply be gone now...)

I think its a vBull option that can be turned on or off by admin. Evidently it has been turned off.
