Showing Update to a Post

There should be a plugin for that.

Post Revision Display
On single post views, this plugin will display a list of all post-publication revisions, showing revision times, authors, and links to view them. When viewing a previous revision, differences (“diffs”) between the previous and current revision will be shown.

That was the one I was looking for! Thanks, Lisa ??

Thanks, but not what I was looking for. I am using WordPress in Joomla. I wanted to know if there is a modular or plugin that I could use that will show a reader my latest updates to any posts.

That’s a Joomla question then.

Thanks.
