I used to be able, until recently, to edit a post several times and the little "last edited [date]" message wouldn't appear at the bottom. Now I can edit it once, and if I do it again after that, the message appears. I liked it better before! Is it possible to change it back?

I like it most when the "last edited [date]" doesn't show up if you change something within a few mniutes after you first posted it.

It gives you the chance to remove some typing errors.
