Since it is already possible to restrict editing mediawiki to regisistered users, seems like a simple, useful thing to add authentication of the email address.
I agree. It'd be a useful feature. And according to Rob Church it's a feature already in the system. It's not the default, because mediawiki is *wiki* software, and it's not a very wiki-like thing to restrict editing.
Could someone explain to me why an email verification of the user that is about to edit on your wiki is restricting editing?!
