Some people are really irritating with retrospective editing.
You can see it if a post is edited after 10 minutes by checking if there is a dotted line under the time post was made. If there is, hover your mouse above the line and you will see who edited it lastly and what time it was edited.
just tryied
but not work for me...
but this functionality it is avaiable just for posts not yours???
chrome 41.0.2272.118 m here.
The post should be edited to see this. It must be edited after 10 minutes to see. Else, you can't see it.
You are using conputer, right? In mobile devices, you can't see but there is an exception if you are using Puffin browser.
Try again by hovering the mouse to dotted line under the time of post creation. Dotted line is visitible for OP.
