What does this plugin do?
Editorize lets you permit a user with the Author or Contributor role to edit any post.
How do I set it up?
After activating the plugin, you’ll notice a new “Post Editor” module in the edit post screen. Simply choose the user you’d like to permit to edit the post:
Then, update the post, or save as draft, and the user you’ve chosen will be able to edit that post.
To revoke their access, simply choose the “Select” option again and update or save the post once more.
