How to confirm:
- Submit an edit suggestion on a post by a user with less than 2K reputation, using a user with less than 2K reputation.
- Sign is as the user receiving the edit suggestion and click the [Edit (1)] link below the post.
- Observe error message denying the user to approve or reject the edit.
- Observe how the edit can be acted upon via the link from receiver's notifications/inbox.
This first arose here, on one of my questions, and was deliberately replicated to test on Ask Ubuntu with an anonymous edit to a post with a 1000-odd rep user.
