No, nobody receives emails when you edit your post. You don’t need to receive emails either; it only depends whether or not you click the appropriate box below your message, or in your Control Panel above.
That said, generally we prefer that you not edit your post too long after it has been posted or referenced by someone else. If one does so, it becomes more difficult to follow the discussion, since other people may end up appearing to respond to a post that no longer exists in its original form.
(I am going to move this thread to another folder, however, and you should receive an email when that happens).
