When a question gets closed, it shows who closed it; if a question gets reopened, it no longer shows who closed it, nor does it show who reopened it. Is there any way to see who reopened it and/or who closed it previously?

The particular example I was looking at is Optimization practice dealing with points on a line.


You can see the history of a post by following the link:


This will be available via the time on the last edited flair:

Where to get the revisions

If there's no last editor you can type the URL yourself, or there is a StackApp which will add a "history" link to all posts.


Check the revision history.

http://<site>/posts/<post id>/revisions

If the question has been edited, click the "edited xyz" link:

I can't find any reopened questions, but https://meta.stackoverflow.com/posts/194/revisions shows the name of the closers--so I guess the usernames of repoeners will be visible as well.


This information is also available via the timeline feature. While there is no direct link to the timeline (unless you use a userscript), it can be constructed quite easily: host name + /posts/ + ID of the question + /timeline.

For this particular question, the URL is https://math.stackexchange.com/posts/140651/timeline
