A user is allowed to edit his question body ---> OK.
He is also allowed to edit his question title ---> Ok, but the link of the question page should not change.
Modifying it can impact on the SEO of the website.
Eg : If the question page has collected many (follow) backlinks from various websites (because the question has answers with value and genuine content), modifying the page address will originate broken links (no more link "juice" to the page...)
Is it possible to have such an option in 1.6.3 ?
(it could be a permission : "changing post/question URL" ---> Admins, Anybody, .....)
