Edited message shown as a new one.

[Limerick]

Hello all,

When a user posts a new thread or a new answer, icons change to show that something has been added.

But, when a post is edited, icons do not change as said above.

So people do not know that a post has been updated.
But I would need everybody to see when a post has been updated.

Then would it be possible to let discussions react exactly in the same manner when one of their posts are edited as when they have a new answer.

This would the same for forums, subforums, etc...

What kind of code modification would allow this, instead of writing "this post has been updated" ?
