Very helpful plugin!

I was updating some links in old posts and then discovered that they were all reposted at the top of the post feed by the date updated. I tried to change the Published date but it was already set to the original date, which was three years ago, but now appeared as if posted today when it was updated. I found this plugin and set the Post Order to be by the Published Date and everything fell back into place in the order published.

Thank you for this plugin!
