Le professionnel d'élite
It was the Original Post in this thread that I was talking about, not the OP of Alexander's Fan Fest.
If a post gets edited, a sentence appears at the end of the post that says when it was last edited. And, if you are the poster or a Mod, this becomes a link which takes you to the post history, telling you how many times it has been edited, and what the differences are. Just the same as the page history on Wikipedia pages.
Sorry for any confusion caused by me not being clear as to what I was talking about.
It's ok and makes sense now. Thank you!
